Chains	Enzyme Name	Description	Catalytic Residues
A	dTDP-6-deoxy-D-xylo-4-hexulose 3,5 epimerase M-CSA #329	dTDP-4-dehydrorhamnose 3,5-epimerase is the third enzyme in the biosynthetic pathway of dTDP-L-rhamnose, a saccharide required for the virulence of some pathogenic bacteria. The pathway does not exist in humans and therefore the enzymes in it are potential drug targets. The enzyme fold is unlike that of any other known epimerase and so represents a novel class of epimerase.
