STRUCTURE OF THE ENDOGLUCANASE CEL6 FROM MYCOBACTERIUM TUBERCULOSIS IN COMPLEX WITH METHYL-CELLOBIOSYL-4-DEOXY-4-THIO-BETA-D-CELLOBIOSIDE AT 1.6 ANGSTROM
Overview
The genomes of various Mycobacterium tuberculosis strains encode proteins, that do not appear to play a role in the growth or survival of the, bacterium in its mammalian host, including some implicated in plant cell, wall breakdown. Here we show that M. tuberculosis H37Rv does indeed, possess a functional cellulase. The x-ray crystal structure of this, enzyme, in ligand complex forms, from 1.9 to 1.1A resolution, reveals a, highly conserved substrate-binding cleft, which affords similar, and, unusual, distortion of the substrate at the catalytic center. The, endoglucanase activity, together with the existence of a putative, membrane-associated crystalline polysaccharide-binding protein, may, reflect the ancestral soil origin of the Mycobacterium or hint at a, previously unconsidered environmental niche.
