ribonuclease


ribonuclease
(= RNAse, RNAase)
Widely distributed type of enzyme that cleaves RNA. May act as endonucleases or exonucleases depending upon the type of enzyme. Generally recognize target by tertiary structure rather than sequence. Ribonuclease E is an RNAase involved in the formation of 5S ribosomal RNA from pre-rRNA. F is stimulated by interferons and cleaves viral and host RNAs and thus inhibits protein synthesis. H specifically cleaves an RNA base-paired to a complementary DNA strand. P is an endonuclease that generate t-RNAs from their precursor transcripts. T is an endonuclease that removes the terminal AMP from the 3\' CCA end of a non-aminoacylated tRNA. RNAase T1 cleaves RNA specifically at guanosine residues. RNAase III cleaves double-stranded regions of RNA molecules.
