TypeCDS
FunctionThought to be involved in transport of undetermined substrate (possibly drug) across the membrane (export): so responsible for the translocation of the substrate across the membrane.
ProductPossible integral membrane efflux protein EfpA
CommentsRv2846c, (MTCY24A1.11), len: 530 aa. Possible efpA, integral membrane efflux protein, member of major facilitator superfamily (MFS) possibly involved in transport of drug (see citations below), equivalent to Q9Z5J5|ML1562|MLCB596.08 putative transmembrane efflux protein from Mycobacterium leprae (534 aa), FASTA scores: opt: 2881, E(): 4.1e-160, (86.55% identity in 535 aa overlap). Also highly similar to several membrane proteins e.g. O69986|SC4H2.31c transmembrane efflux protein (515 aa), FASTA scores: opt: 1063, E(): 2.2e-54, (39.65% identity in 406 aa overlap); Q9FBQ5|SCD86A.02c putative transport integral membrane protein from Streptomyces coelicolor (503 aa), FASTA scores: opt: 918, E(): 5.8e-46, (33.7% identity in 469 aa overlap); Q9KYU0|SCE22.23c putative transmembrane efflux protein from Streptomyces coelicolor (514 aa), FASTA scores: opt: 888, E(): 3.3e-44, (32.85% identity in 469 aa overlap); etc.
Functional categoryCell wall and cell processes
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011).
TranscriptomicsmRNA identified by DNA microarray analysis (gene induced by isoniazid (INH) or ethionamide treatment) (see Wilson et al., 1999). mRNA also identified by other microarray analysis; transcription repressed at low pH in vitro conditions, which may mimic an environmental signal encountered by phagocytosed bacteria (see Fisher et al., 2002).
MutantEssential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
