TRNA nucleotidyltransferase
- TRNA nucleotidyltransferase
In enzymology, a tRNA nucleotidyltransferase (EC number|2.7.7.56) is an enzyme that catalyzes the chemical reaction
:tRNAn+1 + phosphate tRNAn + a nucleoside diphosphate
Thus, the two substrates of this enzyme are tRNA(n+1) and phosphate, whereas its two products are tRNA(n) and nucleoside diphosphate.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is tRNA:phosphate nucleotidyltransferase. Other names in common use include phosphate-dependent exonuclease, RNase PH, and ribonuclease PH.
