Ribonucleic acid (RNA) from torula yeast may be used as a substrate for studying ribonuclease activities of enzymes such as ribonuclease-A, ribonuclease T1 (RNAase) and bougainvillea xbuttiana antiviral protein 1 (BBAP1).
We report on the effect of the viscogenic agents glycerol and ficoll on the RNase T1 catalyzed turnover of GpA, GpC, GpU, and Torula yeast RNA. For wild-type enzyme, we find that the kcat/Km values for the transesterification of GpC
Three nucleosides catalyzing the oxidoreduction of NADH and K3Fe(CN)6 were isolated from Torula yeast RNA and also obtained by a series of steps: SDS-phenol extraction, nuclease P1 digestion, alkaline phosphatase digestion, anion exchange chromatography, and HPLC on an ODS column.
Ribonuclease (RNase), which often represents molecular biological contamination, is a thermostable enzyme. When RNase is heated at 121 degrees C by autoclave sterilization for 20 min, it does not lose its activity. However, the nature of the molecular events by
The review is devoted to the chemical synthesis of oligoribonucleotides and the protecting groups used. In particular the existent methods of blocking 2'-OH function in nucleotide monomers for the RNA synthesis are discussed in detail.
