THE STRUCTURE OF NADH IN THE DTDP-D-GLUCOSE DEHYDRATASE (RMLB) ENZYME
Overview
The structure of Streptococcus suis serotype type 2 dTDP-d-glucose, 4,6-dehydratase (RmlB) has been determined to 1.5 A resolution with its, nicotinamide coenzyme and substrate analogue dTDP-xylose bound in an, abortive complex. During enzyme turnover, NAD(+) abstracts a hydride from, the C4' atom of dTDP-glucose-forming NADH. After elimination of water, hydride is then transferred back to the C6' atom of, dTDP-4-keto-5,6-glucosene-regenerating NAD(+). Single-crystal, spectroscopic studies unambiguously show that the coenzyme has been, trapped as NADH in the crystal. Electron density clearly demonstrates that, in contrast to native structures of RmlB where a flat nicotinamide ring is, observed, the dihydropyridine ring of the reduced cofactor in this complex, is found as a boat.
