Bifunctional arginine dihydrolase/ornithine cyclodeaminase ArgZ

UniProtKB accession:  P74535

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Bifunctional enzyme involved in a cyanobacterial arginine utilization pathway that enables cellular adaptation to nitrogen fluctuations (PubMed:29632414, PubMed:30656751). Catalyzes the hydrolysis of arginine to ornithine, with the release of ammonia and carbon dioxide (PubMed:29632414, PubMed:31914412). Then, probably catalyzes the conversion of ornithine to proline, with the release of ammonia (By similarity). Is highly specific for arginine and cannot hydrolyze citrulline, dimethylarginine and other amino acids (PubMed:29632414).
