THE CRYSTAL STRUCTURE OF GLYCERALDEHYDE 3-PHOSPHATE DEHYDROGENASE FROM ALCALIGENES XYLOSOXIDANS AT 1.7 RESOLUTION.

Overview

The enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from the, Gram-negative denitrifying bacterial species Alcaligenes xylosoxidans was, purified and crystallized as a contaminant protein during purification of, nitrous oxide reductase. This is the first structure of a GAPDH from a, denitrifying species. The crystal structure was solved at 1.7 A resolution, by molecular replacement using the structure of GAPDH from Bacillus, stearothermophilus as a starting model. The quality of the structure, enabled the amino-acid sequence of the A. xylosoxidans GAPDH to be, assigned. The structure is that of the apo-enzyme, lacking the NAD+, cofactor and with the active-site residue Cys154 oxidized. The global, structure of the enzyme has a homotetrameric quaternary structure similar, to that ... [(full description)]
