Gene Rv3097c (PE_PGRS63)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Generates diacylglycerol and a fatty acid anion from triacylglycerol [catalytic activity: triacylglycerol + H(2)O = diacylglycerol + a fatty acid anion]. |
| Product | PE-PGRS family protein, triacylglycerol lipase LipY (esterase/lipase) (triglyceride lipase) (tributyrase) |
| Comments | Rv3097c, (MTCY164.08c), len: 437 aa. LipY, triacylglycerol lipase. Belongs to the hormone-sensitive lipase family (See Deb et al., 2006) and member of the M. tuberculosis PE-family PGRS subfamily of gly-rich proteins (see citation below); N-terminal part similar to N-terminus of M. tuberculosis PE-PGRS family members e.g. Q10637|Y03A_MYCTU hypothetical glycine-rich 49.6 kDa protein (603 aa). Other relatives include MTCY1A11.25c; MTCY21B4.13c; MTCY270.06; MTCY359.33; MTC1A11.04. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007). |
| Functional category | Pe/ppe |
| Proteomics | Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). |
| 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 strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). M. tuberculosis H37Rv with lipY disrupted is impaired in ability to utilize triacylglycerol in nutrient-deprived conditions (See Deb et al., 2006). Check for mutants available at TARGET website |
