General annotation
FunctionThis isozyme is involved in mycolic acid biosynthesis. Second reductive step in fatty acid biosynthesis. Involved in the resistance against the antituberculosis drugs isoniazid and ethionamide [catalytic activity: acyl-[acyl-carrier protein] + NAD(+) = trans-2,3-dehydroacyl-[acyl-carrier protein] + NADH].
ProductNADH-dependent enoyl-[acyl-carrier-protein] reductase InhA (NADH-dependent enoyl-ACP reductase)
CommentsRv1484, (MTCY277.05), len: 269 aa. InhA, NADH-dependent enoyl-[acyl-carrier-protein] reductase (see citations below). Identical to INHA_MYCTU|P46533 enoyl-[acyl-carrier-protein] reductase from Mycobacterium tuberculosis and G1155270 Mycobacterium bovis enoyl acp reductase. Some similarity to the short-chain dehydrogenases/reductases (SDR) family.
Functional categoryLipid metabolism
ProteomicsNote that in Mycobacterium bovis BCG, proteome analysis by 2D-electrophoresis and MS identified this homolog which showed increased expression inside macrophages (see citation below). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). 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 and 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantEssential 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, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
