General annotation
FunctionInvolved in phthiocerol dimycocerosate (dim) biosynthesis. Thought to be involved in the release and transfer of mycoserosic acid from mas onto the DIOLS.
ProductFatty-acid-AMP ligase FadD28 (fatty-acid-AMP synthetase) (fatty-acid-AMP synthase)
CommentsRv2941, (MTCY24G1.08c), len: 580 aa. FadD28 (alternate gene name: acoas), fatty-acid-AMP synthetase (see citations below), almost identical to P71495 acyl-CoA synthase from Mycobacterium bovis (582 aa), FASTA scores: opt: 3828, E(): 0, (99.15% identity in 580 aa overlap); and equivalent to Q9CD79|FADD28|ML0138 acyl-CoA synthetase from Mycobacterium leprae (579 aa), FASTA scores: opt: 3183, E(): 8.8e-186, (81.9% identity in 580 aa overlap). And also highly similar to others Mycobacteria proteins e.g. O07797|FADD23|Rv3826|MTCY409.04c putative fatty-acid-CoA synthetase from Mycobacterium tuberculosis (584 aa); etc. Contains PS00018 EF-hand calcium-binding domain. Note that Rv2941|fadD28 and Rv2942|mmpL7 are transcriptionally coupled (proven experimentally).

ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified 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 culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011).
TranscriptomicsmRNA identified by DNA microarray analysis and possibly down-regulated by hrcA|Rv2374c (see Stewart et al., 2002). Note that in Mycobacterium bovis BCG, Northern blotting analysis and cDNA-totalRNA substractive hybridization strategy reveals increased expression of the corresponding transcript while inside macrophages (see Li et al., 2001).
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 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).
