LITERATURE
transcription of the mtmB1C1 operon is not affected by the nitrogen source but appears to be increased when trimethylamine is the sole carbon and energy source. Under nitrogen limitation, a 543fold up-regulation of the mtmB2C2 operon encoding MMA methyltransferase 2 is obtained when methanol was used as carbon source, whereas transcription of the homologous mtmB1C1 operon occurs at a constant level independently of the nitrogen source
