CRYSTAL STRUCTURE OF THE CONSERVED HYPOTHETICAL PROTEIN RV1873 FROM MYCOBACTERIUM TUBERCULOSIS AT 1.38 A

Overview

The X-ray crystal structure of the gene product encoded by open reading, frame Rv1873 of Mycobacterium tuberculosis has been determined by single, isomorphous replacement with anomalous scattering (SIRAS) phasing, techniques at 1.38 A resolution from monoclinic crystals with unit-cell, parameters a = 33.44, b = 31.63, c = 53.19 A, beta = 90.8 degrees. The, 16.2 kDa Rv1873 is a monomer that adopts a primarily alpha-helical fold, with limited structural similarity to previously determined tertiary, structures. It has been annotated as a conserved hypothetical protein of, unknown function and is classified by the Clusters of Orthologous Groups, (COG) database as belonging to COG5579. The three-dimensional structure of, the Rv1873 gene product reveals limited similarity to a repeated motif, that is found in a variety of other proteins. While not a novel fold, it, serves as a model for orthologues predicted to be related by sequence and, it is hoped that knowledge of the structure of Rv1873 will aid in, determining a possible function for this protein.
