Gene Rv3462c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | No specific function has so far been attributed to this initiation factor; however, it seems to stimulate more or less all the activities of the other two initiation factors, if-2 and if-3. |
| Product | Probable translation initiation factor if-1 InfA |
| Comments | Rv3462c, (MTCY13E12.15c), len: 73 aa. Probable infA, initiation factor if-1, equivalent to P45957|ML1962|INFA translation initiation factor if-1 from Mycobacterium bovis (72 aa) and Mycobacterium leprae (72 aa), FASTA scores: opt: 472, E(): 6.6e-28, (100.0% identity in 72 aa overlap). Also highly similar to others e.g. O54209|IF1_STRCO|INFA|SC6G4.03 from Streptomyces coelicolor (73 aa), FASTA scores: opt: 424, E(): 2e-24, (84.95% identity in 73 aa overlap); O50630|IF1_BACHD|INFA|BH0158 from Bacillus halodurans (71 aa), FASTA scores: opt: 388, E(): 8.1e-22, (77.8% identity in 72 aa overlap); Q9XD14|IF1_LEPIN|INFA from Leptospira interrogans (71 aa), FASTA scores: opt: 376, E(): 6e-21, (80.0% identity in 70 aa overlap); etc. Contains 1 'S1 motif' domain. Belongs to the if-1 family. |
| Functional category | Information pathways |
| Proteomics | Identified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified in the cell membrane fraction 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 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). Disruption of this gene results in growth defect of H37Rv in vitro, 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).
