USTILAGO SPHAEROGENA RIBONUCLEASE U2
Overview
The crystal structure of purine-specific ribonuclease (RNase) U2 from, Ustilago sphaerogena has been solved by the molecular replacement methods, using RNase T1 as a search model. The structure, with 114 amino acid, residues, 141 water molecules, and a sulfate ion, is refined to an R, factor of 0.143 at 1.8 A resolution. As evidenced by the electron, densities, residues 49 and 50 are revised to Glu 49 and Asp 50, respectively, and also Asp 45 is identified as a beta-isomerized form to, L-isoaspartate with a beta-peptide linkage. RNase U2 consists of a, beta-hairpin at residues from 7 to 14, a 4.4-turn alpha-helix from 16 to, 32, a central beta-sheet with five strands, and a protruding beta-turn, from 74 to 77. As for the catalytic site residues, His 41, Glu 62, and Arg, 85 are located as ... [(full description)]
