In the silkworm, Bombyx mori, alanine aminotransferase (AT-ase) was high in the midgut and silkglands, whereas aspartate AT-ase activity was much higher in the midgut and fat body than in the silkglands. Alanine- and aspartate AT-ase activity in the three kinds of tissues were significantly lowered by the deficiency of dietary pyridoxine in the presence or the absence of pyridoxal-P in the incubation medium. The enzyme activities were increased with increasing levels of dietary pyridoxine. However, the increase rates of the activities varied among the three kinds of tissues.
