Abstract:
:Methanomonas methanooxidans incorporates both carbon atoms of acetate into the glutamate and aspartate families of amino acids during growth on methane; carbon dioxide is also evolved from both carbon atoms of acetate. The distribution of carboxyl-labeled acetate incorporated into convalently bound glutamate is consistent with the operation of the tricarboxylic acid cycle in this species, and the presence of alpha-ketoglutarate dehydrogenase was demonstrated in cell-free extracts.
