metabolism | when growing on trimethylamine, nitrogen fixation does not occur in the cells, indicating that ammonium released during trimethylamine degradation is sufficient to serve as a nitrogen source and represses nif gene induction, transcriptional regulation of soluble methyltransferases, which catalyze the initial step of methylamine consumption by methanogenesis, in response to different carbon and nitrogen sources, overview. Transcription of the operon encoding DMA methyltransferase is not regulated in response to the nitrogen source.
