Abstract
A study was done of the pathways of nitrogen assimilation in the facultative methylotrophsPseudomonas MA andPseudomonas AM1, with ammonia or methylamine as nitrogen sources and with methylamine or succinate as carbon sources. When methylamine was the sole carbon and/or nitrogen source, both organisms possessed enzymes of the glutamine synthetase/glutamate synthase pathway, but when ammonia was the nitrogen sourcePseudomonas AM1 also synthesized glutamate dehydrogenase with a pH optimum of 9.0, andPseudomonas MA elaborated both glutamate dehydrogenase (pH optimum 7.5) and alanine dehydrogenase (pH optimum 9.0). Glutamate dehydrogenase and glutamate synthase from both organisms were solely NADPH-dependent; alanine dehydrogenase was NADH-dependent. No evidence was obtained for regulation of glutamine synthetase by adenylylation in either organism, nor did glutamine synthetase appear to regulate glutamate dehydrogenase synthesis.
