1 EC 3.1.26.5: RNase P is a type of ribonuclease that is unique in that it is a ribozyme â a ribonucleic acid that acts as a catalyst in the same way as an enzyme. 2  Its function is to cleave off an extra, or precursor, sequence on tRNA molecules. RNase A (e.g. , bovine pancreatic ribonuclease A: PDB: 2AAS â) is one of the hardiest enzymes in common laboratory usage; one method of isolating it is to boil a crude cellular extract until all enzymes other than RNase A are denatured.
RNA polymerase II of Saccharomyces cerevisiae consisting of all 12 subunits. RNA polymerase II (RNAP II and Pol II) is an enzyme found in eukaryotic cells. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA.A 550 kDa complex of 12 subunits, RNAP II is the most studied type of RNA polymerase. A wide range of transcription factors are required for it to bind to upstream gene promoters and begin transcription.t catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA.
