General annotation
| Type | CDS |
| Function | Unknown. Thought to be involved in fatty acid transport. |
| Product | Probable conserved transmembrane transport protein MmpL4 |
| Comments | Rv0450c, (MTV037.14c), len: 967 aa. Probable mmpL4, conserved transmembrane transport protein (see citations below), member of RND superfamily, equivalent to U1740V|P54881|YV34_MYCLE hypothetical 105.2 kDa protein from Mycobacterium leprae (959 aa), FASTA scores: opt: 5051, E(): 0, (78.4% identity in 962 aa overlap). Also highly similar to other proteins from Mycobacterium tuberculosis e.g. Z83860|MTCY98.08 (962 aa), FASTA scores: opt: 3917, E(): 0, (61.3% identity in 950 aa overlap), MTCY20G9.34, etc. Contains PS00211 ABC transporters family signature. Belongs to the MmpL family. |
| Functional category | Cell wall and cell processes |
| 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 30 days but not 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 4h, 24h and 96h of starvation (see Betts et al., 2002). DNA microarrays indicate repression by iron and IdeR|Rv2711 in M. tuberculosis H37Rv (See Rodriguez et al., 2002). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-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). Non essential gene by Himar1 transposon mutagenesis in CDC1551 strain (see Lamichhane et al., 2003). Essential gene for in vitro growth of H37Rv, and essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011).
