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.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis. Since primase produces RNA molecules, the enzyme is a type of RNA polymerase.Primase functions by synthesizing short RNA sequences that are complementary to a single-stranded piece of DNA, which serves as its template.ince primase produces RNA molecules, the enzyme is a type of RNA polymerase.
