Gene Rv2855 (gorA)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in reduction of mycothiol. |
| Product | NADPH-dependent mycothiol reductase Mtr |
| Comments | Rv2855, (MTCY24A1.02c), len: 459 aa. Mtr, NADPH-dependent mycothiol reductase, proven enzymatically but previously described as glutathione reductase homolog (gene name: gorA) (see citation below). Similar to others e.g. Q9L7K8|MERA mercuric reductase from Streptomyces sp. CHR28 (474 aa), FASTA scores: opt: 719, E(): 9e-38, (35.2% identity in 460 aa overlap); P30341|MERA_STRLI mercuric reductase from Streptomyces lividans (474 aa), FASTA scores: opt: 712, E(): 2.5e-37, (34.95% identity in 455 aa overlap); Q98ED5|MLL4296 ferric leghemoglobin reductase-2 precursor, dihydrolipoamide dehydrogenase from Rhizobium loti (Mesorhizobium loti) (468 aa), FASTA scores: opt: 670, E(): 1.1e-34, (30.8% identity in 471 aa overlap); etc. Belongs to the pyridine nucleotide-disulphide oxidoreductases class-I. Cofactor: FAD. |
| 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). |
| 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). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website |
