Structural highlights

1pm7 is a 2 chain structure with sequence from "bacillus_tuberculosis"_(zopf_1883)_klein_1884 "bacillus tuberculosis" (zopf 1883) klein 1884. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:,
Gene:rmlc (rfbc) ("Bacillus tuberculosis" (Zopf 1883) Klein 1884)
Activity:dTDP-4-dehydrorhamnose 3,5-epimerase, with EC number 5.1.3.13

Function

[RMLC_MYCTU] 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. Involved in the biosynthesis of the dTDP-L-rhamnose which is a component of the critical linker, D-N-acetylglucosamine-L-rhamnose disaccharide, which connects the galactan region of arabinogalactan to peptidoglycan via a phosphodiester linkage.[1]

Publication Abstract from PubMed

The emergence of multi-drug resistant tuberculosis, coupled with the increasing overlap of the AIDS and tuberculosis pandemics has brought tuberculosis to the forefront as a major worldwide health concern. In an attempt to find new inhibitors of the enzymes in the essential rhamnose biosynthetic pathway, a virtual library of 2,3,5 trisubstituted-4-thiazolidinones was created. These compounds were then docked into the active site cavity of 6'hydroxyl; dTDP-6-deoxy-D-xylo-4-hexulose 3,5-epimerase (RmlC) from Mycobacterium tuberculosis. The resulting docked conformations were consensus scored and the top 5% were slated for synthesis. Thus far, 94 compounds have been successfully synthesized and initially tested. Of those, 30 (32%) have > or =50% inhibitory activity (at 20 microM) in the coupled rhamnose synthetic assay with seven of the 30 also having modest activity against whole-cell M. tuberculosis.
