The molecular evolution of pancreatic ribonuclease
Journal of Molecular Evolution, 1977The primary structures of pancreatic ribonucleases from 26 species (18 artiodactyls, horse, whale, 5 rodents and turtle) are known. Several species contain identical ribonucleases (cow/bison; sheep/goat), other species show polymorphism (arabian camel) or the presence of two structural gene loci (guinea pig pancreas contains two ribonucleases that ...

The interaction of DNA with pancreatic ribonuclease A
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1969Abstract 1. 1. The complex formation of calf thymus DNA with pancreatic ribonuclease A (ribonucleate pyrimidinenucleotido-2′-transferase (cycling), EC 2.7.7.16) was studied through ultracentrifugation, competitive inhibition of ribonuclease activity and gel filtration on Sephadex G-200.

Crystallization of mouse pancreatic ribonuclease
Journal of Molecular Biology, 1988Mouse pancreatic ribonuclease has been crystallized in a form suitable for X-ray structure determination. The crystals grown from solutions of 2-methyl-2,4-pentanediol diffract to high resolution and belong to the hexagonal space group P6(1) (P6(5)) with unit cells dimensions a = b = 64.44 A, c = 53.91 A, y = 120 degrees and V = 1.94 x 10(5) A3 (1 A ...

Publisher Summary This chapter reviews recent data on several aspects of the catalytic mechanism of pancreatic RNases as well as some molecular properties such as carbohydrate content and folding and unfolding pathways. This chapter begins with a discussion on reaction catalyzed by pancreatic ribonucleases.

Ribonuclease of bovine milk: Serological relationship to pancreatic ribonuclease
Archives of Biochemistry and Biophysics, 1964Abstract 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.

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 ...

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

Pancreatic Ribonuclease Distribution and Comparisons in Mammals
Nature New Biology, 1973PANCREATIC RNAase is absent or present in very small amounts in the pancreas of species such as man, cat, seal and rabbit1. Likewise no RNAase activity has been found in the pancreatic juice of dog by Marchis-Mouren et al.2 and in the juice of cat and rabbit by Berndt3.

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1986
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 ...

Biological Function of Pancreatic Ribonuclease
Nature, 1969The physiological function of this much studied pancreatic enzyme has been misunderstood. It is essential only in ruminants and certain other herbivores, where it has a special function.
