Effect of bovine seminal ribonuclease and bovine pancreatic ribonuclease A on bovine oocyte maturation

Journal of Experimental Zoology, 2000
Bovine seminal ribonuclease (BS-RNase) contains the MxM (noncovalent dimer) and M=M (free monomer) in constant ratio. The aim of this work was to evaluate the effect of BS-RNase, its monomer and dimer forms, and also various mutants of this enzyme on meiotic completion in cattle oocytes.

Semisynthetic studies on bovine pancreatic ribonuclease

International Journal of Peptide and Protein Research, 1984
The S‐peptide of the enzyme bovine pancreatic ribonuclease has been used as a model for covalent semisynthesis. Methods for side‐chain protection, enzymatic cleavage of the peptide chain at the level of the single arginine‐10 and for selective deprotection of the α‐carboxyl function of this residue, have been examined.

Dinitrophenylation and inactivation of bovine pancreatic ribonuclease A

Archives of Biochemistry and Biophysics, 1965
Abstract The dinitrophenylation of bovine pancreatic ribonuclease A at pH 8.0, 15 °C is confined in its initial stages to the modification of lysine residues. The sites of attack are the α-amino group of the N-terminal lysine residue and the ϵ-amino groups of the lysine residues in positions 7 and 41. The most reactive amino group is that at position

Ribonuclease of bovine milk: Serological relationship to pancreatic ribonuclease

Archives of Biochemistry and Biophysics, 1964
Abstract Ribonuclease isolated from bovine milk has been shown to be serologically identical to pancreatic ribonuclease. The presence of ribonuclease in milk was demonstrated directly by a gel-diffusion method. The serological method employed did not detect ribonuclease in bovine serum.

Calculations of the CD spectrum of bovine pancreatic ribonuclease

Biopolymers, 1997
CD spectra of bovine pancreatic ribonuclease A (RNase A) and its subtilisin-modified from (RNase S) have been calculated, based upon high-resolution structures from x-ray diffraction. All known transitions in the peptide and side-chain groups, especially the aromatic and disulfide groups, have been included.

Conformational Flexibility of Bovine Pancreatic Ribonuclease A

Journal of the Physical Society of Japan, 1983
Conformational energies of native ribonuclease A were computed in the multi-dimensional space of dihedral angles of the backbone and side chains. By minimization of the total energy starting from three sets of the angles, we obtained three low energy conformations, C1, C2 and C3, which have almost the same energy, -644±4 kcal/mol and are close to the ...

Chemical synthesis of bovine pancreatic ribonuclease A

Journal of the Chemical Society, Chemical Communications, 1980
Bovine pancreatic ribonuclease, which consists of 124 amino acids, was synthesized in a conventional manner by assembling relatively small 30-peptide fragments of established purity.
