General annotation
FunctionInvolved in fatty acid biosynthesis (mycolic acids synthesis) [catalytic activity: ATP + propionyl-CoA + CO(2) + H(2)O = ADP + orthophosphate + methylmalonyl-CoA].
ProductAcetyl/propionyl-CoA carboxylase (beta subunit) AccD6
CommentsRv2247, (MTCY427.28), len: 473 aa. AccD6, Acetyl/Propionyl CoA Carboxylase, beta subunit (see citations below), highly similar to e.g. PCCB_RHOSO|Q06101 propionyl-CoA carboxylase beta chain, FASTA score: (75.1% identity in 437 aa overlap). Similar to many other Acetyl/Propionyl CoA Carboxylases from Mycobacterium tuberculosis. Belongs to the AccD / PccB family.
Functional categoryLipid metabolism
ProteomicsIdentified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Translational start site supported by proteomics data (See Kelkar 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 and real-time RT-PCR; transcription up-repressed at low pH in vitro conditions, which may mimic an environmental signal encountered by phagocytosed bacteria (see Fisher et al., 2002). mRNA also identified by microarray analysis and up-regulated after 96h of starvation (see Betts et al., 2002).
MutantDisruption of this gene results in growth defect of H37Rv in vitro, 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).
