Affinity Labeling of Pancreatic Ribonuclease
Abstract Pyridoxal phosphate can be firmly bound by reduction with sodium borohydride to many enzymes in which it occurs. Such treatment has been used to label specifically parts of peptide chains in the vicinity of the bound coenzyme. Pyridoxal phosphate may form specific complexes with many proteins for which it has no known coenzyme function. Bovine

Acid ribonuclease activity of hepatoma cells [PDF]
Activities of intracellular RNase of the liver cytoplasm, normal liver cells exposed to 3'-Me-DAB and heaptoma cells, have been studied in correlation with the contents of RNA and DNA and morphologic changes of the cells with or without treating RNase ...

Construction of Highly Stable Cytotoxic Nuclear-Directed Ribonucleases
Ribonucleases are proteins whose use is promising in anticancer therapy. We have previously constructed different human pancreatic ribonuclease variants that are selectively cytotoxic for tumor cells by introducing a nuclear localization signal into ...

NMR studies on structure and dynamics of the monomeric derivative of BS-RNase: new insights for 3D domain swapping. [PDF]
Three-dimensional domain swapping is a common phenomenon in pancreatic-like ribonucleases. In the aggregated state, these proteins acquire new biological functions, including selective cytotoxicity against tumour cells.
