In enzymology, a dTDP-4-amino-4,6-dideoxygalactose transaminase (EC 2.6.1.59) is an enzyme that catalyzes the chemical reaction
- dTDP-4-amino-4,6-dideoxy-D-galactose + 2-oxoglutarate [math]\displaystyle{ \rightleftharpoons }[/math] dTDP-4-dehydro-6-deoxy-D-galactose + L-glutamate
Thus, the two substrates of this enzyme are dTDP-4-amino-4,6-dideoxy-D-galactose and 2-oxoglutarate, whereas its two products are dTDP-4-dehydro-6-deoxy-D-galactose and L-glutamate.
This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is dTDP-4,6-dideoxy-D-galactose:2-oxoglutarate aminotransferase. Other names in common use include thymidine diphosphoaminodideoxygalactose aminotransferase, and thymidine diphosphate 4-keto-6-deoxy-D-glucose transaminase. It employs one cofactor, pyridoxal phosphate.
