Description dTDP-3-dehydro-6-deoxy-D-glucose aminotransferase
Notes Only one functionally validated gene product (from T. thermosaccharolyticum).

These bacterial enzymes are phylogenetically related to (and very difficult to distinguish from ) a number of other NDP-hexose aminotransferases, in particular DesV.
