Crystal structure of a bacterial ribonuclease P RNA.
The x-ray crystal structure of a 417-nt ribonuclease P RNA from Bacillus stearothermophilus was solved to 3.3-A resolution. This RNA enzyme is constructed from a number of coaxially stacked helical domains joined together by local and long-range interactions. These helical domains are arranged to form a remarkably flat surface, which is implicated by a wealth of biochemical data in the binding ...
متن کاملOcta-O-propanoyl-beta-maltose: crystal structure, acyl stacking, related structures, and conformational analysis.
The crystal structure of beta-maltose octapropanoate (1) was solved to improve understanding of di-, oligo-, and polysaccharide conformations. The O6 and O6' atoms are in gg and gt orientations, respectively. Extrapolation of the coordinates of the non-reducing residue and observed linkage bond and torsion angles of 1 [Formula: see text] yields a left-handed helix similar to amylose triacetate ...
متن کاملConformational flexibility of Mycobacterium tuberculosis thioredoxin reductase: crystal structure and normal-mode analysis.
The thioredoxin system exists ubiquitously and participates in essential antioxidant and redox-regulation processes via a pair of conserved cysteine residues. In Mycobacterium tuberculosis, which lacks a genuine glutathione system, the thioredoxin system provides reducing equivalents inside the cell. The three-dimensional structure of thioredoxin reductase from M. tuberculosis has been determin...
متن کاملLigand-induced conformational changes in ribonuclease.
The rate of formation of ribonuclease-S from ribonuclease A by the action of subtilisin was measured at pH 5.5 in the presence and absence of the strongly bound ribonuclease inhibitor, 2’-cytidylate. Presence of the inhibitor in the active center significantly reduced the rate of formation of ribonuclease-S. Since bond 20-21 (and, to a lesser extent, 21-22), the cleavage of which is responsible...
متن کاملRefinement of the crystal structure of ribonuclease S. Comparison with and between the various ribonuclease A structures.
Ribonuclease S (RNase-S) is a complex that consists of two proteolytic fragments of bovine pancreatic ribonuclease A (RNase-A): the S-peptide (residues 1-20) and S-protein (residues 21-124). We have refined the crystal structures of three RNase-S complexes. The first two contain the full-length 20-residue S-peptide and were studied at pHs of 4.75 and 5.5. The third one consists of a truncated f...
