RIBONUCLEASE A-URIDINE VANADATE COMPLEX: HIGH RESOLUTION RESOLUTION X-RAY STRUCTURE (1.3 A)

Overview

The X-ray crystal structure of a uridine vanadate-ribonuclease A complex, has been determined at 1.3 A resolution. The resulting structure includes, all 124 amino-acid residues, a uridine vanadate, 131 water molecules, and, a single bound 2-methyl-2-propanol. Side chains of 11 surface residues, showing discrete disorder were modeled with multiple conformations. The, final crystallographic R factor is 0.197. Structures obtained from, high-level ab initio quantum calculations of model anionic oxyvanadate, compounds were used to probe the effects of starting structure on the, refinement process and final structure of the penta-coordinate phosphorane, analog, uridine vanadate. The least-squares refinement procedure gave rise, to the same final structure of the inhibitor despite significantly, ... [(full description)]
