in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown; lipolytic enzyme involved in cellular metabolism. |
| Product | Probable esterase/lipase LipF |
| Comments | Rv3487c, (MTCY13E12.41c), len: 277 aa. Probable lipF, esterase/lipase (see citation below), highly similar, but shorter 50 aa, to O53424|LIPU|Rv1076|MTV017.29 putative esterase/lipase from Mycobacterium tuberculosis (297 aa), FASTA scores: opt: 1229, E(): 3.3e-71, (76.4% identity in 246 aa overlap); and similar to other putative lipases from Mycobacterium tuberculosis e.g. P71759|LIPK|RV2385|MTCY253.36c (306 aa), FASTA scores: opt: 468, E(): 1.2e-22, (36.2% identity in 254 aa overlap). Equivalent, but shorter 79 aa, to Q9ZBM4|MLCB1450.08|ML0314 putative hydrolase (putative esterase) from Mycobacterium leprae (335 aa), FASTA scores: opt: 1225, E(): 6.6e-71, (73.6% identity in 250 aa overlap). Also similar to esterases and lipases of around 300 aa e.g. Q44087|est esterase precursor from Acinetobacter lwoffii (303 aa), FASTA scores: opt: 428, E(): 4.3e-20, (31.85% identity in 251 aa overlap); P18773|EST_ACICA esterase from Acinetobacter calcoaceticus (303 aa), FASTA scores: opt: 420, E(): 1.4e-19, (31.5% identity in 251 aa overlap); Q9KIU1 esterase from uncultured bacterium Plasmid pAH116 (308 aa), FASTA scores: opt: 405, E(): 1.3e-18, (35.1% identity in 242 aa overlap); Q9X8J4|SCE9.22 putative esterase from Streptomyces coelicolor (266 aa), FASTA scores: opt: 390, E(): 1e-17, (35.85% identity in 237 aa overlap); etc. Equivalent to AAK47950 from Mycobacterium tuberculosis strain CDC1551 (327 aa) but shorter 50 aa. |
| Functional category | Intermediary metabolism and respiration |
| Transcriptomics | DNA microarrays show higher level of expression in M. tuberculosis H37Rv than in phoP|Rv0757 mutant (See Walters et al., 2006). DNA microarrays show increased expression in M. tuberculosis H37Rv in BALB/c mice compared to SCID mice, after 21 days of infection (See Talaat et al., 2004). |
| 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 |
