Enzyme Information

2.7.7.56
tRNA nucleotidyltransferase.
based on mapping to UniProt Q81LA9
tRNA(n+1) + phosphate = tRNA(n) + a nucleoside diphosphate.
-!- Brings about the final exonucleolytic trimming of the 3'-terminus of tRNA precursors in Escherichia coli by a phosphorolysis, producing a mature 3'-terminus in tRNA and nucleoside diphosphate. -!- Not identical with EC 2.7.7.8.
