Serum Deoxyribonuclease and Ribonuclease in Pancreatic Cancer and Chronic Pancreatitis
Tumori Journal, 1985Serum ribonuclease (RNase) and deoxyribonuclease (DNase) were investigated in 18 control subjects, and in 22 patients with pancreatic cancer, 13 with chronic pancreatitis and 29 with extrapancreatic diseases in order to assess their clinical usefulness in pancreatic cancer diagnosis and to evaluate whether modifications were consensual and/or age ...

Kinetic constants for the transesterification of eight dinucleoside phosphates CpX and UpX by bovine and turtle pancreatic ribonuclease were determined. Both ribonucleases have a preference for purine nucleotides at the position X. However, bovine ribonuclease, like other mammalian ribonucleases, prefers 6-amino bases at this site, while turtle ...

The inhibition of pancreatic ribonuclease by anionic polymers
Archives of Biochemistry and Biophysics, 1959Abstract The inhibition of pancreatic ribonuclease by ten sulfate-containing polymers has been examined. Sulfated corn amylose (13.9% S) and sulfated polyvinyl alcohol (17.2% S) were the most effective compounds. With sulfated corn amylose the inhibition was shown to be of the competitive type.

Stereochemistry of the transesterification step of pancreatic ribonuclease
Biochemical and Biophysical Research Communications, 1972Summary Determination by X-ray analysis of the absolute configuration of uridine 3′-O-thiophosphate methyl ester obtained by the reaction of uridine 2′,3′-O,O-cyclothiophosphate with pancreatic ribonuclease in aqueous methanol, establishes an inline mechanism for the transesterification reaction of this enzyme.

The ribonuclease activity of crystallized pancreatic deoxyribonuclease
Analytical Biochemistry, 1966Abstract Chromatography of crystallized pancreatic DNase on DEAE-cellulose separates DNase of high specific activity from an inactive protein fraction and the bulk of RNase activity. The RNase fraction that resisted physical separation from DNase could be preferentially inactivated by iodoacetate.

Semisynthetic studies on bovine pancreatic ribonuclease
International Journal of Peptide and Protein Research, 1984The 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, 1965Abstract 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

Biosynthesis of pancreatic ribonuclease
2012Methods have been developed for the study of amino acid incorporation into a specific protein under established conditions of net synthesis. The results of these studies have been reported and discussed. Synthesis and storage of the secretory proteins of mouse pancreas have been shown to occur between fifteen to twenty-one hours after pilocarpine ...

Publisher Summary Bovine Ribonuclease has been a test protein in the study of a wide variety of chemical and physical methods of protein chemistry. It is widely employed in the course of the sequencing of RNA. This chapter discusses the usefulness of the cytoplasmic inhibitor of RNase to protect RNA in the course of the synthesis of complementary DNA
