THE HIGH RESOLUTION STRUCTURE OF MYCOBACTERIUM TUBERCULOSIS LEUB (RV2995C)


Overview

The crystal structure of the enzyme 3-isopropylmalate dehydrogenase (IPMDH) from Mycobacterium tuberculosis (LeuB, Mtb-IPMDH, Rv2995c) without substrate or co-factor was determined at 1.65 A resolution, which is the highest resolution reported for an IPMDH to date. The crystals contain two functional dimers in the asymmetric unit in an arrangement close to a tetramer of D2 symmetry. Despite the absence of a substrate or inhibitor bound to the protein, the structure of the monomer resembles the previously observed closed form of the enzyme more closely than the open form. A comparison with the substrate complex of IPMDH from Thiobacillus ferrooxidans and the co-factor complex of the Thermus thermophilus enzyme revealed a close relationship of the active-site architecture between the various bacterial enzymes. The inhibitor O-isobutenyl oxalylhydroxamate was found to bind to the active site of IPMDH in a mode similar to the substrate isopropylmalate.
