FunctionInvolved in phenolpthiocerol and phthiocerol dimycocerosate (dim) biosynthesis: extension with malony CoA (complete reduction).
ProductPhenolpthiocerol synthesis type-I polyketide synthase PpsC
CommentsRv2933, (MTCY19H9.01, MTV011.02), len: 2188 aa. ppsC, type-I polyketide synthase (see citations below), highly similar to others from Mycobacterium leprae e.g. Q49933|PKSD|ML2355|L518_F1_3 putative polyketide synthase (2201 aa), FASTA scores: opt: 6973, E(): 0, (82.32% identity in 2217 aa overlap); Q49624|PKS3|MASA|ML1229|B1170_C2_209 probable mycocerosic acid synthase (2118 aa), FASTA scores: opt: 4015, E(): 2.9e-208, (36.6% identity in 2184 aa overlap); etc. Also similar to polyketide synthases from other bacteria e.g. C-terminus of Q9L8C7 polyketide synthase from Polyangium cellulosum (7257 aa), FASTA scores: opt: 3909, E(): 3.6e-202, (40.15% identity in 2220 aa overlap); Q9KIZ7|EPOD EPOD protein from Polyangium cellulosum (7257 aa), FASTA scores: opt: 3886, E(): 6.2e-201, (40.05% identity in 2220 aa overlap); etc. And also highly similar to others from Mycobacterium tuberculosis e.g. P96291|Rv2940c (2111 aa), FASTA scores: opt: 4204, E(): 0, (39.1% identity in 2176 aa overlap); Q10977|PPSA_MYCTU|RV2931 phenolpthiocerol synthesis polyketide synthase (1876 aa), FASTA scores: opt: 3793, E(): 2.4e-196, (46.65% identity in 1612 aa overlap); etc. Contains PS00606 Beta-ketoacyl synthases active site, and PS00012 Phosphopantetheine attachment site. Note that Rv2933|ppsC belongs to the transcriptional unit Rv2930|fadD26-Rv2939|papA5 (proven experimentally).
Functional categoryLipid metabolism
ProteomicsIdentified in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 and 90 days (See Kruh et al., 2010). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011).
TranscriptomicsmRNA identified by microarray analysis and down-regulated after 24h of starvation (see Betts et al., 2002).
MutantNon-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 strain (see Sassetti et al., 2003). Essentialgene by Himar1 transposon mutagenesis in CDC1551 strain (see Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
