Alteration in acitivities of ammonium assimilation enzymes in Micrococcus luteus (IF03333) in accordance with the changes in cultural conditions was investigated. The activity of alanine dehydrogenase (AlaDH) was high and the considerable activities of GOT and GPT were found, while the activity of glutamate dehydrogenase was low and aspartase, glutamine synthetase and glutamate synthese were not active. Alanine extremely increased the activity of Ala DH when utilized as the nitrogen or carbon sources or when added to culture medium. The activity of Ala DH was inhibited by glutamic acid, aspartic acid and glucose in culture medium. The alteration of the activity of GPT responding to culture conditions was somewhat similar to that of Ala DH but the activity of this enzyme was not inhibited by glucose in culture medium. The activity of GOT was activated by glutamic acid and aspartic acid but was inhibited by alanine in culture medium.
