Gene Rv0436c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in phospholipid biosynthesis. Generates phosphatidylserine [catalytic activity: CDP-diacylglycerol + L-serine = CMP + O-SN-phosphatidyl-L-serine]. |
| Product | Probable CDP-diacylglycerol--serine O-phosphatidyltransferase PssA (PS synthase) (phosphatidylserine synthase) |
| Comments | Rv0436c, (MTCY22G10.33c), len: 286 aa. Probable pssA, PS synthase (CDP-diacylglycerol--serine O-phosphatidyltransferase) (see citation below), integral membrane protein, equivalent to AL035159|MLCB1450_9|T44730 from Mycobacterium leprae (300 aa), FASTA scores: opt: 1506, E(): 0, (77.9% identity in 285 aa overlap). Also highly similar to others e.g. NP_108059.1|14027250|BAB54204.1|AP003012 phosphatidylserine synthase from Mesorhizobium loti (248 aa); PSS_BACSU|P39823 cdp-diacylglycerol--serine o-phosphatidyltransferase from Bacillus subtilis (177 aa), FASTA scores: opt: 277, E(): 9.9e-12, (33.3% identity in 183 aa overlap); etc. Contains PS00379 CDP-alcohol phosphatidyltransferases signature. Belongs to the CDP-alcohol phosphatidyltransferase class-I family. |
| Functional category | Lipid metabolism |
| Proteomics | Predicted transmembrane protein - identified in culture filtrates of M. tuberculosis H37Rv; signal peptide predicted (See Malen et al., 2007). |
| 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 CDC1551 strain (see Lamichhane et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
