Gene Rv2429
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in oxidative stress response. LPDC|Rv0462, DLAT|Rv2215, AHPD|Rv2429, and AHPC|Rv2428 constitute an NADH-dependent peroxidase and peroxynitrite reductase that provides protection against oxidative stress. |
| Product | Alkyl hydroperoxide reductase D protein AhpD (alkyl hydroperoxidase D) |
| Comments | Rv2429, (MTCY428.17c), len: 177 aa. AhpD, alkyl hydroperoxide reductase, similar to other alkyl hydroperoxide reductases D proteins e.g. Q9RN73|AHPD from Streptomyces coelicolor (178 aa), FASTA scores: opt: 611, E(): 1.4e-33, (57.4% identity in 169 aa overlap); Q50441|AHPD_MYCSM AHPD protein (fragment) from Mycobacterium smegmatis (52 aa), FASTA score: opt:196. |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified by proteomics (see Rosenkrands et al., 2000). Identified 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 the culture filtrate and membrane protein fraction of M. tuberculosis H37Rv but not whole cell lysates (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis; transcription up-regulated at low pH in vitro conditions, which may mimic an environmental signal encountered by phagocytosed bacteria (see Fisher et al., 2002). |
| Mutant | Non-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 strain (see Sassetti et al., 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
