General annotation
| Type | CDS |
| Function | Involved in post-incision events. In addition to DNA polymerase activity, this DNA polymerase exhibits 3' to 5' and 5' to 3' exonuclease activity [catalytic activity: N deoxynucleoside triphosphate = N diphosphate + {DNA}(N)]. |
| Product | Probable DNA polymerase I PolA |
| Comments | Rv1629, (MTCY01B2.21), len: 904 aa. Probable polA, DNA polymerase I (see citations below). Has DNA polymerase family a signature (PS00447) at C-terminal end. FASTA best: DPO1_MYCTU|Q07700 DNA polymerase I from Mycobacterium tuberculosis (904 aa). Some similarity to Rv2090|MTCY49.30 (393 aa), E(): 2.2e-18, (38.7% identity in 292 aa overlap). Belongs to DNA polymerase type-a family. |
