tRNA nucleotidyltransferase activity https://github.com/geneontology/go-ontology/issues/19854 https://github.com/geneontology/go-ontology/issues/24408 https://github.com/geneontology/go-ontology/issues/30193 Note that, although EC names the enzme tRNA nucleotidyltransferase, the enzyme to which this term refers is also known as 'ribonuclease PH', and degrades tRNA in the 3'-5' direction in vivo. It should not be confused with CCA tRNA nucleotidyltransferase. molecular_function Catalysis of the reaction: tRNA(n+1) + phosphate = tRNA(n) + a nucleoside diphosphate. ribonuclease PH activity RHEA:10628 MetaCyc:TRNA-NUCLEOTIDYLTRANSFERASE-RXN phosphate-dependent exonuclease activity EC:2.7.7.56 RNase PH activity GO:0009022 nucleotidyltransferase activity catalytic activity, acting on a tRNA
