Gene Rv3496c
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 Mce4D |
| Comments | Rv3496c, (MTV023.03c), len: 451 aa. Mce4D; belongs to 24-membered Mycobacterium tuberculosis Mce protein family (see citations below), highly similar to Mycobacterium tuberculosis proteins O07416|Rv0172|MTCI28.12|mce1D (530 aa); O07786|Rv0592|MTCY19H5.30c|mce2D (508 aa); and O53970|Rv1969|MTV051.07|mce3D (423 aa). Also similar to others e.g. Q9CD11|MCE1D|ML2592 putative secreted protein from Mycobacterium leprae (531 aa), FASTA scores: opt: 837, E(): 2.6e-34, (34.55% identity in 446 aa overlap); Q9F359|SC8A2.04c putative secreted protein from Streptomyces coelicolor (337 aa), FASTA scores: opt: 606, E(): 4.9e-23, (32.35% identity in 300 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 |
| 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 strain (see Sassetti 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).
