>gnl|CDD|58620 cd04254, AAK_UMPK-PyrH-Ec, UMP kinase (UMPK)-Ec, the microbial/chloroplast uridine monophosphate kinase (uridylate kinase) enzyme that catalyzes UMP phosphorylation and plays a key role in pyrimidine nucleotide biosynthesis; regulation of this process is via feed-back control and via gene repression of carbamoyl phosphate synthetase (the first enzyme of the pyrimidine biosynthesis pathway). The UMP kinase of E. coli (Ec) is known to function as a homohexamer, with GTP and UTP being allosteric effectors. Like other related enzymes (carbamate kinase, aspartokinase, and N-acetylglutamate kinase) the E. coli and most bacterial and chloroplast UMPKs (this CD) have a conserved, N-terminal, lysine residue proposed to function in the catalysis of the phosphoryl group transfer, whereas most archaeal UMPKs appear to lack this residue and the Pyrococcus furiosus structure has an additional Mg ion bound to the ATP molecule which is proposed to function as the catalysis instead. Members of this CD belong to the Amino Acid Kinase Superfamily (AAK).. Length = 231
