General annotation
TypeCDS
FunctionHydrolyzes sphingomyelin in addition to phosphatidylcholine. Probable virulence factor implicated in the pathogenesis of M.tuberculosis at the level of intracellular survival, by the alteration of cell signaling events or by direct cytotoxicity [catalytic activity: a phosphatidylcholine + H(2)O = 1,2- diacylglycerol + choline phosphate].
ProductProbable phospholipase C 4 (fragment) PlcD
CommentsRv1755c, (MT1799, MTCY28.21c), len: 280 aa. Probable plcD, phospholipase C 4 (fragment) (see citations below), highly similar to C-terminus of other phospholipases e.g. CQ50771|Rv2351c|PLCA|MTP40|MT2416|MTCY98.20c phospholipase C 1 from Mycobacterium tuberculosis (512 aa), FASTA score: (71.1% identity in 284 aa overlap); etc. Note that this ORF has been interrupted by insertion of IS6110 element. Belongs to the bacterial phospholipase C family.
Functional categoryIntermediary metabolism and respiration
MutantNon-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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Found to be deleted (partially or completely) in one or more clinical isolates (See Tsolaki et al., 2004).
