phosphate-dependent tRNA nucleotidyltransferase and polynucleotide phosphorylase activity play an essential role that affects ribosome metabolism, this function cannot be taken over by any of the hydrolytic exonucleases present in the cell |
| 2.7.7.56 | more |
for 16S rRNA degradation during glucose starvation, leading to slow cell growth, begins with shortening of its 3' end in a reaction catalyzed by RNase PH |
| 2.7.7.56 | tRNAn+1 + phosphate |
reverse reaction is synthetic |
| 2.7.7.56 | tRNAn+1 + phosphate |
brings about the final exonucleolytic trimming of the 3'-terminus of tRNA precursors in E. coli by phosphorolysis, producing a mature 3'-terminus on tRNA and nucleoside diphosphate |
| 2.7.7.56 | tRNAn+1 + phosphate |
implicated in the 3'-processing of tRNA precursors |
| 2.7.7.56 | tRNAn+1 + phosphate |
role in tRNA processing and RNA degradation |
| 2.7.7.56 | tRNAn+1 + phosphate |
catalyzes the removal of nucleotides at the 3' end of the tRNA precursor, leading to the release of nucleoside diphosphate, and generates the CCA end during the maturation process |
| 2.7.7.56 | tRNAn+1 + phosphate |
involved in the maturation of tRNA precursors and especially important for removal of nucleotide residues near the CCA acceptor end of the mature tRNAs |
| 2.7.7.56 | tRNAn+1 + phosphate |
plays a major role in the exonucleolytic maturation of CCA-containing tRNA precursors, degradation of the last few nucleotides before the acceptor stem |
| 2.7.7.56 | tRNAn+1 + phosphate |
degradation of 16S rRNA substrate 3' end |
