ProductIsoniazid inductible gene protein IniA
CommentsRv0342, iniA, (MTCY13E10.02), len: 640 aa. IniA, isoniazid-inducible gene, (see citations below). Shows slight similarity to some hypothetical bacterial proteins e.g. P40983|YOR6_THER hypothetical protein (402 aa), FASTA scores: opt: 242, E(): 1.4e-07, (22.3% identity in 349 aa overlap). Also some similarity to downstream ORF Rv0343|iniC. Possible transmembrane stretch around residue 490. Alternative start site exists at 410824. Contains a phosphopantetheine attachment site motif suggestive of an acyl carrier protein. Note that the iniA gene is also induced by the antibiotic ethambutol, an agent that inhibits cell wall biosynthesis by a mechanism that is distinct from isoniazid.
Functional categoryCell wall and cell processes
ProteomicsIdentified by proteomics at the Statens Serum Institute (Denmark) (see Rosenkrands et al., 2000). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS; predicted transmembrane protein (See Gu et al., 2003). Identified in the cell wall and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010).
TranscriptomicsmRNA identified by DNA microarray analysis (gene induced by isoniazid (INH) or ethionamide treatment) (see Wilson et al., 1999). Quantitative PCR shows INH-mediated induction of iniB|Rv0341, iniA|Rv0342 and iniC|Rv0343 is repressed in M. tuberculosis H37Rv overexpressing lsr2|Rv3597c (See Colangeli et al., 2007).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
