Gene Rv1814
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in lipid desaturation |
| Product | Membrane-bound C-5 sterol desaturase Erg3 (sterol-C5-desaturase) |
| Comments | Rv1814, (MTCY1A11.29c), len: 300 aa. Erg3, transmembrane C-5 sterol desaturase (see *), weak similarity to several e.g. ERG3_YEAST|P32353 c-5 sterol desaturase (365 aa), FASTA scores: opt: 154, E(): 0.0011, (22.9% identity in 288 aa overlap). Belongs to the sterol desaturase family. [* Note: work of Jackson, C.J., Lamb, D.C., Kelly, D.E., Kelly, S.L., Characterization of a sterol delta 5,6-desaturase homolog in Mycobacterium bovis (BCG). Submitted (jun-2000) to the EMBL/GenBank/DDBJ databases]. |
| Functional category | Lipid metabolism |
| Mutant | Non-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 provides a growth advantage 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, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
