Gene Rv1402
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Recognizes a specific hairpin sequence on PHIX SSDNA; this structure is then recognized and bound by proteins PRIB and PRIC. Formation of the primosome proceeds with the subsequent actions of DNAB, DNAC, DNAT and primase. PRIA then functions as a helicase within the primosome |
| Product | Putative primosomal protein N' PriA (replication factor Y) |
| Comments | Rv1402, (MTCY21B4.19), len: 655 aa. Putative priA, primosomal protein N'. Similar to e.g. PRIA_ECOLI|P17888 primosomal protein N' (replication factor Y) (732 aa), FASTA scores, opt: 386, E(): 1.3e-16, (27.6% identity in 711 aa overlap). Compared to other bacterial priA, it has a very divergent helicase domain. Belongs to the helicase family. PRIA subfamily. |
| Functional category | Information pathways |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
