Gene Rv2391
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Catalyzes the reduction of sulfite to sulfide, in the biosynthesis of sulfur-containing amino acids and co-factors |
| Product | Ferredoxin-dependent sulfite reductase SirA |
| Comments | Rv2391, (MTCY253.30c), len: 563 aa. SirA, ferredoxin-dependent sulfite reductase (See Schnell et al., 2005). Previously annotated as nirA. Similar to e.g. CAC33947|SCBAC1A6.26c Putative nitrite/sulphite reductase from Streptomyces coelicolor (565 aa), FASTA scores: opt: 2335, E(): 1.2e-137, (60.1% identity in 567 aa overlap); Q9RZD6|DRA0013 ferredoxin-nitrite reductase from Deinococcus radiodurans (563 aa), FASTA scores: opt: 1141, E(): 2.2e-63, (39.6% identity in 533 aa overlap); Q59656|NIRA (D31732|PEENIRNRT_1) ferredoxin-dependent nitrite reductase from Plectonema boryanum (654 aa) (see Suzuki & Kikuchi 1995), FASTA scores: opt: 805, E(): 1.9e-42, (31.7% identity in 517 aa overlap); Q55366|NIRA|SLR0898 ferredoxin-nitrite reductase from Synechocystis sp. strain PCC 6803 (502 aa), FASTA scores: opt: 799, E(): 3.7e-42, (32.3% identity in 517 aa overlap); etc. Highly similar (only in N-terminal part because shortened protein (fragment) owing to an IS900 insertion) to Q9K541|NIRA nitrate reductase (fragment) from Mycobacterium paratuberculosis (198 aa), FASTA scores: opt: 798, E(): 2.1e-42, (65.4% identity in 182 aa overlap) (see Bull et al., 2000). |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | 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, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). |
| Transcriptomics | DNA microarrays show higher level of expression in M. tuberculosis H37Rv than in phoP|Rv0757 mutant (See Walters et al., 2006). |
| Mutant | 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). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003).. Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
