| Primary Identifier | IPR010206 | Type | Family |
| Short Name | PolA_pol_I |
| description | This entry describes poly(A) polymerase I (also known as PcnB and plasmid copy number protein). These enzymes sequentially add adenosine nucleotides to the 3' end of RNAs, targeting them for degradation by the cell [, ]. This was originally described for anti-sense RNAs, but was later demonstrated for mRNAs as well []. Members of this family are predominantly found in the gamma- and beta-proteobacteria, with putative members in the Chlamydiacae and Spirochetes. This family has homology to tRNA nucleotidyltransferase. |
