ribokinase |
<enzyme> Substrate ribose may be replaced by deoxyribose Registry number: EC 2.7.1.15 Synonym: deoxyribokinase (26 Jun 1999) |
ribonuclease |
<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 E is involved in the formation of 5S ribosomal RNA from pre rRNA. Ribonuclease F is stimulated by interferons and cleaves viral and host RNA and thus inhibits protein synthesis. Ribonuclease H specifically cleaves an RNA base paired to a complementary DNA strand. Ribonuclease P is an endonuclease that generate t RNA from their precursor transcripts. 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. Acronym: RNase (23 Aug 1998) |
ribonuclease (Bacillus subtilis) |
1. Ribonuclease (Azotobacter agilis); ribonuclease (Proteus mirabilis); an enzyme catalyzing the endonucleolytic cleavage of RNA to yield 2',3'-cyclic nucleotides. 2. Ribonuclease T1. (05 Mar 2000) |
ribonuclease (pancreatic) |
|
ribonuclease D |
<enzyme> An enzyme (endonuclease) that trims the extra 3' nucleotides from immature tRNA. (05 Mar 2000) |
ribonuclease h, calf thymus |
<enzyme> A ribonuclease that specifically cleaves the RNA moiety of RNA:DNA hybrids. It has been isolated from a wide variety of prokaryotic and eukaryotic organisms (particularly calf thymus) as well as retroviruses. Registry number: EC 3.1.26.4 (12 Dec 1998) |
ribonuclease t1 |
<enzyme> An enzyme catalyzing the endonucleolytic cleavage of RNA at the 3'-position of a guanylate residue. Chemical name: Ribonucleate 3'-guanylo-oligonucleotidohydrolase Registry number: EC 3.1.27.3 (12 Dec 1998) |
ribonuclease, pancreatic |
<enzyme> An enzyme that catalyses the endonucleolytic cleavage of pancreatic ribonucleic acids to 3'-phosphomono- and oligonucleotides ending in cytidylic or uridylic acids with 2',3'-cyclic phosphate intermediates. Registry number: EC 3.1.27.5 (12 Dec 1998) |
ribonucleases |
<enzyme> Enzymes that catalyze the hydrolysis of ester bonds within RNA. Registry number: EC 3.1.- (12 Dec 1998) |
ribonucleic acid |
<molecular biology> A nucleic acid found in all living cells. Plays a role in transferring information from DNA to the protein-forming system of the cell. (16 Dec 1997) |
ribonucleinase |
<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 E is involved in the formation of 5S ribosomal RNA from pre rRNA. Ribonuclease F is stimulated by interferons and cleaves viral and host RNA and thus inhibits protein synthesis. Ribonuclease H specifically cleaves an RNA base paired to a complementary DNA strand.

Ribonuclease T1 cleaves RNA specifically at guanosine residues. Ribonuclease TIII cleaves double stranded regions of RNA molecules. Acronym: RNase (23 Aug 1998) |
ribonucleoprotein |
<protein> Complexes of RNA and protein involved in a wide range of cellular processes. Besides ribosomes (with which ribonucleoprotein was originally almost synonymous), in eukaryotic cells both initial RNA transcripts in the nucleus (hnRNA) and cytoplasmic mRNAs exist as complexes with specific sets of proteins. Processing (splicing) of the former is carried out by small nuclear ribonucleoproteins (snRNP). Other examples are the signal recognition particle responsible for targetting proteins to endoplasmic reticulum and a complex involved in termination of transcription. Acronym: RNP (23 Aug 1998) |
