>TIGR00746 arcC carbamate kinase; InterPro: IPR003964 The arginine dihydrolase (AD) pathway is found in many prokaryotes and some primitive eukaryotes. The three- enzyme anaerobic pathway breaks down L-arginine to form 1 mol of ATP, carbon dioxide and ammonia. In simpler bacteria, the first enzyme, arginine deiminase, can account for up to 100f total cell protein . Carbamate kinase is involved in the last step of the AD pathway, converting carbamoyl phosphate and ADP into ammonia, carbon dioxide and ATP . The second step of the pathway involves the degradation of L-citrulline to carbamoyl phosphate and L-ornithine, using ornithine carbamoyltransferase . The crystal structure of Enterococcus faecium carbamate kinase has been determined to 2.8A resolution . The enzyme exists as a homodimer of two 33kDa subunits. The hallmark of the dimer is a 16-stranded beta-sheet, surrounded by alpha-helices. Each subunit contains an active site within a large crevice.; GO: 0008804 carbamate kinase activity, 0006525 arginine metabolic process.
