Description dTDP-4-dehydro-6-deoxy-D-glucose aminotransferase (2.6.1.-)
Notes A rather heterogeneous family based on the validated enzymes from Escherichia coli O7, Shigella dysenteriae Type 7 and Streptomyces sp.
The family is related to other aminotransferases involved in aminosugar metabolism (DesV, ArnB) and to perosamine aminotransferase.
