A transferase that catalyzes the hydrolysis of ribonucleic acid.An enzyme that catalyses the depolymerization of RNA.ribonuclease
(Science: Biochemistry, Enzyme, Molecular biology) Widely distributed type of enzyme that cleaves rNA. May act as endonucleases or exonucleases depending upon the type of enzyme. Generally recognise target by tertiary structure rather than sequence.
Ribonuclease T is an endonuclease that removes the terminal aMP from the 3' cCA end of a nonaminoacylated tRNA. Ribonuclease T1 cleaves rNA specifically at guanosine residues. Ribonuclease TIII cleaves double stranded regions of RNA molecules.
