Ribonuclease S redux.
The S-peptide and S-protein components of bovine pancreatic ribonuclease form a noncovalent complex with restored ribonucleolytic activity. Although this archetypal protein-fragment complementation system has been the object of historic work in protein chemistry, intrinsic limitations compromise its utility. Modern methods are shown to overcome those limitations and enable new applications.
متن کاملStudies on Ribonuclease S
Specific regions of the polypeptide sequence of pancreatic ribonuclease have been altered by chemical modification and by limited proteolytic digestion in attempts to implicate specific covalent portions of the molecule in the structure and stabilization of the active center. Digestion of the native molecule with trypsin at elevated temperatures has been shown to remove portions of the chain wi...
متن کاملCrystalline semisynthetic ribonuclease-S'.
Crystals of solid phase-derived semisynthetic ribonuclease-S' were prepared and compared with those for native ribonuclease-S' and -S. The semisynthetic species used was the noncovalent complex of synthetic fragment-(1-20), corresponding to residues 1 through 20 of bovine pancreatic ribonuclease-A (ribonucleate 3'-pyrimidino-oligonucleotidohydrolase, EC 3.1.4.22), and native ribonuclease-S-(21-...
متن کاملReading Aloud: Discrete Stage(s) Redux
Interactive activation accounts of processing have had a broad and deep influence on cognitive psychology, particularly so in the context of computational accounts of reading aloud at the single word level. Here we address the issue of whether such a framework can simulate the joint effects of stimulus quality and word frequency (which have been shown to produce both additive and interactive ef...
متن کاملOptical activity of cystine-containing proteins. II. Circular dichroism spectra of pancreatic ribonuclease A, ribonuclease S, and ribonuclease S-protein.
The circular dichroism spectra of pancreatic ribonuclease A, RNase S, and RNase S-protein have been measured in the wave length interval 198 to 300 mp under various conditions. The circular dichroism spectra of RNase A and S are very similar, possibly identical, over this entire wave length interval at neutral pH. That of RNase S-protein is substantially different. It is shown that the portion ...
