Optical 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 ...
متن کاملTheoretical study of magnetic susceptibility and optical activity of small molecules containing one chiral center
In the first part of this work, correlation between optical activity and elements of magnetic susceptibility tensor (MST) for five classes of model small molecules containing a single chiral center has been studied using quantum computational techniques at DFT-B3LYP level of theory with 6-311G basis set. Several molecular properties are used to reduce the MST elements prior to the examination o...
متن کاملCystine in human serum proteins.
FEW QUANTITATIVE ANALYSES of cystine in human serum protein fractions have been recorded in the literature, since cystine cannot be determined easily by microbiologic assay or paper chromatography. Brand and his coworkers (1, 2, 3) have reported the amount of cystine and cysteine in a few protein fractions using phosphotungstate and iodometric methods, but few results have been given using the ...
متن کاملFormation of Cystine Slipknots in Dimeric Proteins
We consider mechanical stability of dimeric and monomeric proteins with the cystine knot motif. A structure based dynamical model is used to demonstrate that all dimeric and some monomeric proteins of this kind should have considerable resistance to stretching that is significantly larger than that of titin. The mechanisms of the large mechanostability are elucidated. In most cases, it originat...
متن کاملDissociation of copper(II) ternary complexes containing cystine.
The collision-induced dissociations are reported for Cu(II) complexes containing 1,4,7-triazacyclononane (tacn) as the auxiliary ligand and a peptide containing one cystine residue. For six of the complexes examined, cleavage of the S-S bond in the peptide was the dominant fragmentation pathway. The exceptions were for complexes containing the largest peptides, (GlyCys'Gly)(2) and (GlyGlyCys')(...
