Gene Rv3498c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown, but thought to be involved in host cell invasion. Predicted to be involved in lipid catabolism. |
| Product | Mce-family protein Mce4B |
| Comments | Rv3498c, (MTV023.05c), len: 350 aa. Mce4B; belongs to 24-membered Mycobacterium tuberculosis Mce protein family (see citations below), highly similar to Mycobacterium tuberculosis proteins O07414|Rv0170|MTCI28.10|mce1B (346 aa); O07788|Rv0590|MTCY19H5.32c|mce2B (275 aa); and O53968|Rv1967|MTV051.05|mce3B (342 aa). Also similar to others e.g. Q9CD13|MCE1B|ML2590 putative secreted protein from Mycobacterium leprae (346 aa), FASTA scores: opt: 803, E(): 6.1e-41, (41.05% identity in 346 aa overlap); Q9F357|SC8A2.06c putative secreted protein from Streptomyces coelicolor (354 aa), FASTA scores: opt: 624, E(): 3.4e-30, (32.55% identity in 338 aa overlap); etc. Hydrophobic region at N-terminus. Predicted to be an outer membrane protein (See Song et al., 2008). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| 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). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011).
