Several aminoalcohols (structural analogues of choline) were capable of converting the inactive form of pneumococcal autolysin to the active form
in vitro. 2-dimethy laminoethanol, 3-dimethylamino-1-propanol, 2-diethylaminoethanol, and choline were most effective, but
N-methyldiethanolamine, 2-ethylaminoethanol, and
N-methylethanoIamine were much less effective. The conversion of E-amidase to the active form by these aminoalcohols was observed at 37°C, in contrast to that by the enzyme substrate, cell walls containing choline, which required incubation at 0-4 °C. All these aminoalcohols inhibited the hydrolytic activity of the active autolysin.

The low molecular weight, inactive form of pneumococcal amidase called E-amidase showed the full activity and a high molecular mass (> 500 kDa) when the enzyme was incubated with high concentrations of choline followed by the removal of excess choline. Before the removal of choline, the enzyme showed a low molecular mass-material (about 36 kDa) similar to that of the original E-amidase, suggesting that the aggregation of the protein took place upon the removal of choline. Furthermore, the addition of choline to the native C-amidase (active form) which had a high molecular mass (> 500 kDa) caused dissociation to a low molecular mass enzyme (about 36 kDa) in the presence of choline. These dissociated enzymes reaggregated upon the removal of choline.

To study the heat-induced gelation mechanism of human serum albumin (HSA), the relationship between the initiation temperature of the unfolding and the phase separation temperature was measured with the HSA solutions containing various amounts of guanidine hydrochloride. The phase separation and network formation processes of polyacrylamide derivatives' solutions and gelatin solutions were also investigated to simulate the protein gelling reaction.
We found that the phase separation and network formation processes of the model compounds resembled those of the unfolded HSA molecules. These results suggested again that the phase separation of HSA resulted from the unfolded molecules, and that the network formation was derived from crosslinking among the dispersed coacervate particles in the dilute solution phase.

A novel lysozyme inhibitor, hen egg white lysozyme inhibitor (Hewli) was isolated from the culture broth of a bacterium (strain I-139) identified as
Bacillus subtilis. Maximum lysozyme inhibitory activity was obtained when the bacterium was grown aerobically in a medium consisting of 0.65 % glucose, 0.5 % sodium glutamate, 1 % meat extract, and 4 % Polypepton (pH 7.0), at 30°C after 30 to 35 hr. Hewli was purified 69-fold from the culture supernatant of
B. subtilis I-139 by ammonium sulfate fractionation, DEAE-Sephadex A-50 column chromatography, Sephacryl S-200 gel chromatography, DEAE-Toyopearl 650M column chromatography, affinity chromatography on a column of immobilized egg white lysozyme, and acetone extraction. The purified lysozyme inhibitor has an amino acid composition of aspartic acid, glutamic acid, valine, and leucine in a 1:1:1:4 molar ratio and fatty acid composition of palmitic acid and/or vaccenic acid. Hewli inhibited
B. subtilis I-139 glycanase and animal lysozymes such as the hen, turkey, or human enzymes.

Rats starved for 3 days were refed a lysine-excess diet for 3, 5, 7, 10, and 15 days, and then examined for changes in potassium levels in the urine, gastrocnemius muscle, liver, serum, and intestine. The urinary excretion of potassium was markedly raised for 2 days after the start of refeeding on the lysine-excess diet, but more prolonged refeeding had little or no effects on the urinary excretion of potassium. The potassium content in the gastrocnemius muscle after refeeding for 3, 5, or 10 days was lower in the lysine-excess group than in the basal group, although that in the liver was significantly higher in the lysine-excess group after refeeding for 3 or 7 days. No changes in the potassium content in the gastrocnemius muscle were observed after refeeding for 15 days, while the serum potassium was lowered in rats refed the lysine-excess diet for 5 or 7 days. The sodium contents in the urine and some organs tested were almost unchanged irrespective of lysine loading throughout the experimental period, with a few exceptions. Thus, these results indicated that refeeding on excess lysine caused a transient increase in the urinary potassium excretion, suggesting that most of the potassium would have been released from the muscle.

Fresh rice grains were dried after harvest by three different drying methods (natural, dehumidified-air, and heated-air drying), and changes in the tipid contents and lipid metabolizing enzyme activities were investigated after storage at 4°C and ambient temperature. The contents of triacylglycerols and phospholipids in the grains decreased after 15 months storage at ambient temperature. In the case of heated-air drying at 50°C, the decrease was the largest. However, marked changes were not found in the grains stored at 4°C. Electron micrographs of the spherosome particles showed that some deformation and fusion occurred in the grains with the heated-air drying at 50 °C after 6 and 12 months of storage. However, such changes in spherosomes were distinctly suppressed in the grains dried by the dehumidified-air dryer at 30 °C. It is noted from this evidence that the conditions of post-harvest drying of fresh rice grains markedly influence the deterioration of rice grains in storage.

The effects of temperature, shear rate, shear time, and concentration on the rheological properties of 11S globulin in ionic strength 0.5, pH 7.6 phosphate buffer were studied by a cone and plate viscometer at shear rates up to 384 sec
-1. The secondary structure changes caused by elevated temperature and shearing were also monitored by Fourier transform infrared spectroscopy (FTIR). The effects of concentration on apparent viscosity were pronounced. A 3-percent solution behaved as a Newtonian solution. The solutions become pseudoplastic when the concentrations were higher than 5 %. The effects of shearing time up-to 30min on apparent viscosity also depended on the concentration. Shear thinning first become nearly time-independent, later was observed in 5 or 10% solution, while 3 % and 20 % solutions behaved as time independent. Increasing temperature at 1.4°C/min with shearing time up to 40min result in the 3, 5, and 10% solutions behaving with shear thinning earlier and with shear thickening later. The reason that elevation temperature and longer shear time caused shear thickening in the solution was a change of secondary structure seen in the FTIR spectrum. The amount of a-helix of 11S globulin increased from 7.8% to 19.6 or 28.1 % as the temperature increased from 25°C to 80 or 90°C, respectively.

Adrenal cortical hormone seems to play an important role in
de novo NAD biosynthesis from tryptophan. Therefore, the effects of prednisolone, a synthetic adrenal cortical hormone, on the urinary excretion of nicotinamide and such catabolic metabolites as N
1-methyhiicotinamide (MNA), N
1-methyl-2-pyridone-5-carboxamide (2-Py) and N
1-methyl-4-pyridone-3-carboxamide (4-Py) were investigated. Rats fed with a niacin-free diet were intraperitoneally injected with prednisolone (3mg/rat) three times at 09:00, 13:00 and 17:00 hr on day 0. As a result, the urinary excretion of nicotinamide, MNA, 2-Py and 4-Py was each higher in the prednisolone group than in the physiological saline group (for control) after 1 day; however, each excretion was lower in the prednisolone group than in control group after 3, 4, 5 and 6 days. On around the 7th day, the urinary excretion in the prednisolone group was restored to the control values. The initial rapid increase and subsequent decrease in the urinary excretion of nicotinamide and its metabolites by an injection of prednisolone is considered to be attributable to a respective elevation of the liver tryptophan oxygenase level and the liver aminocarboxymuconate-semialdehyde decarboxylase level.

The L-sorbosone pathway for 2-keto-L-gulonic acid (2KGA) formation from L-sorbose in
Gluconobacter melanogenus IFO 3293 was confirmed. L-Sorbose dehydrogenase, which catalyzes the conversion of L-sorbose to L-sorbosone, was found in the membrane fraction of the microorganism, and L-sorbosone dehydrogenase in the cytosol fraction. The latter enzyme requires NAD or NADP as a cofactor.
2KGA was reduced to L-idonic acid by 2KGA reductase, but L-idonic acid was re-oxidized to 2KGA by membrane-bound L-idonate dehydrogenase.

Satsuma mandarin juice, the concentrated juice and the acid-free juice were prepared and treated with pressures of 1000-6000 bar after mixing with organic acids, various yeasts and molds, or pectinesterase, to study the effects of pressure on inactivation of microorganisms and the enzyme. The effects of heat treatment were also studied in similar conditions. As results, the inactivation effect of pressure on microorganisms and the enzyme was decreased by increasing juice concentration. Pressure-induced inactivation of microorganisms was not affected by either juice pH (between 2.5 and 4.5) or kinds of organic acids (citric, tartaric, lactic, or acetic acid). With 9 species of yeasts and molds tested, pressurization at 3500 bar for 30 min or at 4000 bar for 5 min was required to reduce them to 1/10
5 or below 1/10
5. Microorganisms resistant to heat tend to be highly resistant to pressure. Although no complete inactivation of pectinesterase was attained after pressurization at 3000 or 4000 bar for 10 min, the partly inactivated enzyme did not recover under ordinary conditions of storage and transportation.

Quantitative structure-activity relationship (QSAR) analyses of the 3-nitro-2, 4, 6-trihydroxybenzamide and thioamide derivatives in the inhibition of photosynthetic electron transport (PET) revealed that the activity would depend largely on the overall lipophilicity of the molecules, and their mode of inhibition would be similar to those of the 3-acyl analogues. However, some of the compounds had higher pI
50 values than those estimated by the equations obtained from the QSAR analysis, indicating that those compounds may bind to the site in a more specific manner than the others would do.

O-methylrhamnose was strictly localized in the acidic polysaccharide which predominantly contained glucuronic acid. Thus, this acidic polysaccharide can be called a cell-wall teichuronic acid and this is the first report of teichuronic acid in spore-forming actinomycetes. This teichuronic acid did not replace teichoic acid which contained phosphate instead of uronic acid, despite the high phosphate concentrations in the growth medium.

Emodin (1, 3, 8-trihydroxy-6-methyl-9, 10-anthraquinone) is a natural occurring anthraquinone formed in rhubarb and fungal metabolites. Emodin was transformed into 6 major metabolites by rat hepatic microsomes. The metabolites were identified as 2-hydroxyemodin, 4-hydroxyemodin, 5-hydroxyemodin, 7-hydroxyemodin, ω-hydroxyemodin, and emodic acid by comparison with the synthetic compounds using thin-layer chromatography. It was clear that 2-hydroxyemodin is a proximate mutagen as a synthetic compound by the
Salmonella assay. Other metabolites, such as 5-hydroxyemodin and ω-hydroxyemodin, became active after metabolic activation, but 4-hydroxyemodin and emodic acid were inactive either in the presence or in the absence of the metabolic activation system.

Upon the phosphorylation (2mol/mol 11S AS), the Ca
2+ -sensitivity of 11S AS decreased and the emulsion properties were improved. On the other hand, the foaming properties and pH-solubility were not so affected. In the interaction with Ca
2+, 11S AS were found to become resistant to Ca

An electron microscopic observation using anti-human lactoferrin (LF) and gold probe and a reverse hemolytic plaque assay using anti-LF serum were done with the aim of clarifying uptake of LF by B lymphocytes and its release from the cells. The electron microscopic observation clearly demonstrated the occurrence of LF inside of the B lymphocyte. The number of LF-secreting cells, measured by a reverse hemolytic plaque assay, varied with cell types; a human-human hybridoma 9P13-2 showed the highest number, but the number was much lower with a mouse myeloma. The number of LF-secreting cells increased in proportion to the incubation period with LF. From these results, we concluded that B lymphocytes incorporated LF and then re-secreted it gradually to the extracellular medium.
