Abstract
Acid phosphatase of sweet potato root tissue was found to consist of five components by die thylaminoethyl-cell ulose column chromatography, and each component was isolated by the rechromatography. They were not separated by Sephadex G-200 gel filtration. All components hydrolyzed various phosphate compounds including phosphomonoester- and pyrophosphate-linkages. Their optimum pH values were in the range of pH 5 to 6. However, there were observed some differences in optimum pH, Michaelis constant for various substrates and relative maximum velocity among the components.
