    Abstract:
    Regulation of aspartate kinase and diaminopimelate decarboxylase activities in Streptococcus bovis and Enterococcus faecium cell-free extracts was studied. The levels of synthesis of aspartate kinase and diaminopimelate decarboxylase in both microorganisms are growth-dependent. The synthesis of these enzymes is depressed by lysine, but the activity of aspartate kinase is induced by addition of this amino acid and threonine to the reaction system. Meso-diaminopimelate dehydrogenase activity was not found in the extracts of Streptococcus bovis and Enterococcus faecium. The data excludes the possibility of lysine formation via six enzyme reactions.
