Английская Википедия:D-amino-acid transaminase
Шаблон:Infobox enzyme In enzymology, a D-amino-acid transaminase (Шаблон:EC number) is an enzyme that catalyzes the chemical reaction:
- D-alanine + 2-oxoglutarate <math>\rightleftharpoons</math> 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.
