D-amino-acid transaminase : ウィキペディア英語版 | D-amino-acid transaminase
In enzymology, a D-amino-acid transaminase () is an enzyme that catalyzes the chemical reaction: :D-alanine + 2-oxoglutarate pyruvate + D-glutamate Thus, the two substrates of this enzyme are D-alanine and 2-oxoglutarate, whereas its two products are pyruvate and D-glutamate. This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is D-alanine:2-oxoglutarate aminotransferase. Other names in common use include D-aspartate transaminase, D-alanine aminotransferase, D-aspartic aminotransferase, D-alanine-D-glutamate transaminase, D-alanine transaminase, and D-amino acid aminotransferase. This enzyme participates in 6 metabolic pathways: lysine degradation, arginine and proline metabolism, phenylalanine metabolism, d-arginine and d-ornithine metabolism, d-alanine metabolism, and peptidoglycan biosynthesis. It employs one cofactor, pyridoxal phosphate. ==Structural studies==
As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , , and .
