FunctionInvolved in sulfolipid-1 (SL-1) biosynthesis
ProductPossible conserved polyketide synthase associated protein PapA2
CommentsRv3820c, (MTCY409.10), len: 468 aa. Possible papA2, conserved polyketide synthase (PKS) associated protein, highly similar to Q49618|PAPA3|ML1230|B1170_C1_180 PKS-associated protein A3 from Mycobacterium leprae (471 aa), FASTA scores: opt: 1660, E(): 2.7e-102, (53.95% identity in 456 aa overlap). Also similar to Q9F2R3|SCD65.19c hypothetical 52.8 KDA protein from Streptomyces coelicolor (473 aa), FASTA scores: opt: 575, E(): 1.8e-30, (27.8% identity in 464 aa overlap); and weakly similar to part of other proteins. Also high similarity with other PKS-associated proteins from Mycobacterium tuberculosis; O50438|PAPA3|Rv1182|MTV005.18 (472 aa), FASTA scores: opt: 1694, E(): 1.5e-104, (53.8% identity in 461 aa overlap); and O07799|PAPA1|Rv3824c|MTCY409.06 (511 aa), FASTA scores: opt: 1664, E(): 1.6e-102, (53.9% identity in 462 aa overlap); and similar to C-terminal end of O53902|PAPA4|Rv1528c|MTV045.02 (165 aa), FASTA scores: opt: 186, E(): 4.1e-05, (37.9% identity in 66 aa overlap).
Functional categoryLipid metabolism
ProteomicsIdentified 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).
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). Essential gene for in vitro growth of H37Rv on cholesterol, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Virulence of M. tuberculosis Erdman mutant in BALB/c mice is unaffected (See Kumar et al., 2007).
