RMLC S. SUIS WITH DTDP-RHAMNOSE

OverviewOverview

The striking feature of carbohydrates is their constitutional, conformational and configurational diversity. Biology has harnessed this, diversity and manipulates carbohydrate residues in a variety of ways, one, of which is epimerization. RmlC catalyzes the epimerization of the C3' and, C5' positions of dTDP-6-deoxy-D-xylo-4-hexulose, forming, dTDP-6-deoxy-L-lyxo-4-hexulose. RmlC is the third enzyme of the rhamnose, pathway, and represents a validated anti-bacterial drug target. Although, several structures of the enzyme have been reported, the mechanism and the, nature of the intermediates have remained obscure. Despite its relatively, small size (22 kDa), RmlC catalyzes four stereospecific proton transfers, and the substrate undergoes a major conformational change during the, course of ...
