Catabolic NAD-specific glutamate dehydrogenase RocG

UniProtKB accession:  P39633

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Devoted to catabolic function of glutamate (and other amino acids of the glutamate family) utilization as sole nitrogen source. It is not involved in anabolic function of glutamate biosynthesis since B.subtilis possesses only one route of glutamate biosynthesis from ammonia, catalyzed by glutamate synthase. Wild-type cells are unable to utilize glutamate or glutamine as a sole carbon source; thus RocG does not function physiologically to synthesize glutamate, but it is involved in the utilization of arginine, and proline as carbon or nitrogen source (PubMed:9829940). The catabolic RocG is essential for controlling gltAB expression via an inhibitory interactions with the transcriptional regulator GltC in response to the availability of sugars (PubMed:17183217, PubMed:15150224).
