Gene Rv0001
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (DNAA box): 5'-TTATC(C/A)A(C/A)A-3'. DNAA binds to ATP and to acidic phospholipids. DNAA protein binds the origin of replication (oriC), ATP and ADP, and exhibited weak ATPase activity. |
| Product | Chromosomal replication initiator protein DnaA |
| Comments | Rv0001, (MT0001, MTV029.01, P49993), len: 507 aa. dnaA, chromosomal replication initiator protein (see citations below), equivalent to other Mycobacterial chromosomal replication initiator proteins. Also highly similar to others except in N-terminus e.g. Q9ZH75|DNAA_STRCH chromosomal replication initiator protein from Streptomyces chrysomallus (624 aa). Contains PS00017 ATP/GTP-binding site motif A (P-loop) and PS01008 DnaA protein signature. Belongs to the DnaA family. Note that the first base of this gene has been taken as base 1 of the Mycobacterium tuberculosis H37Rv genomic sequence. |

| Proteomics | Identified in the cell wall and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). |
| 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). 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).
