• Dihydropteroate synthetase was widely distributed in the higher plants tested, and a high enzyme activity was found in green leaves. In the early germination stage in pea seedlings, most of the enzyme activity existed in the cotyledon. With growth, a remarkable increase in enzyme activity in the root plus shoot was observed. The amount of Streptococcus faecalis R-active substances in root plus shoot rapidly increased during the germination of pea seedlings.A large percentage of the enzyme activity was located in the mitochondrial fractions of both pea and soybean seedlings. Most of the S. faecalis R-active substances in pea seedlings existed in the soluble fraction from the cytoplasm.
