|---|---|
| RNA, transfer, tyr | A transfer RNA which is specific for carrying tyrosine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, val | A transfer RNA which is specific for carrying valine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, viral | Ribonucleic acid that makes up the genetic material of viruses. (12 Dec 1998) |
| RNA-binding proteins | Proteins which bind to RNA molecules. Certain structure motifs are common to several of the proteins, such as arginine (arg)-rich tracts, typically consisting of alternating arg-asp, arg-ser, or arg-gly residues. These proteins also tend to have a common ribonucleotide sequence domain. (12 Dec 1998) |
| RNA-dependent ATPase | <enzyme> Requires single-stranded polynucleotide as cofactor Registry number: EC 3.6.1.- Synonym: atpase, RNA-dependent (26 Jun 1999) |
| RNA-directed DNA polymerase | <enzyme> An enzyme that synthesises DNA on an RNA template. It is encoded by the pol gene of retroviruses and by certain retrovirus-like elements. Chemical name: Deoxynucleotide-triphosphate:DNA deoxynucleotidyltransferase (RNA-directed) Registry number: EC 2.7.7.49 (12 Dec 1998) |
| RNA-tyrosine phosphatase | <enzyme> Hela cell enzyme which removes 5'-terminal protein from poliovirus RNA by breaking the tyrosine-phosphate bond between the above two entities Registry number: EC 3.1.4.- Synonym: uridylyl-(5'p-o)-tyrosine phosphodiesterase, y-pupnpde, tyrosine-RNA phosphatase, uridylylpolynucleotide-(5'p-o)-tyrosine phosphodiesterase (26 Jun 1999) |
