REFINED STRUCTURE OF THE COMPLEX BETWEEN GUANYLATE KINASE AND ITS SUBSTRATE GMP AT 2.0 ANGSTROMS RESOLUTION


Overview

The crystal structure of guanylate kinase from Saccharomyces cerevisiae complexed with its substrate GMP has been refined at a resolution of 2.0 A. The final crystallographic R-factor is 17.3% in the resolution range 7.0 A to 2.0 A for all reflections of the 100% complete data set. The final model has standard geometry with root-mean-square deviations of 0.016 A in bond lengths and 3.0 in bond angles. It consists of all 186 amino acid residues, the N-terminal acetyl group, the substrate GMP, one sulfate ion and 174 water molecules. Guanylate kinase is structurally related to adenylate kinases and G-proteins with respect to its central beta-sheet with connecting helices and the giant anion hole that binds nucleoside triphosphates. These nucleotides are ATP and GTP for the kinases and GTP for the G-proteins. The chain segment binding the substrate GMP of guanylate kinase differs grossly from the respective part of the adenylate kinases; it has no counterpart in the G-proteins. The binding mode of GMP is described in detail. Probably, the observed structure represents one of several structurally quite different intermediate states of the catalytic cycle.
