Gene Rv1471 (trxB)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Thioredoxin participates in various redox reactions through the reversible oxidation of its active center dithiol, to a disulfide, & catalyzes dithiol-disulfide exchange reactions. |
| Product | Probable thioredoxin TrxB1 |
| Comments | Rv1471, (MTV007.18), len: 123 aa. Probable trxB1, thioredoxin, similar to many bacterial thioredoxins e.g. P33636|THI2_ECOLI from Escherichia coli (139 aa), FASTA scores: opt: 290, E(): 1.8e-13, (44.3% identity in 97 aa overlap); etc. Highly similar to Rv1470|TrxA probable thioredoxin from Mycobacterium tuberculosis (124 aa), FASTA scores: opt: 402, E(): 1.2e-32, (54.4% identity in 114 aa overlap). Contains PS00194 Thioredoxin family active site. Belongs to the thioredoxin family. Note that previously known as trxB. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by DNA microarray analysis and up-regulated at high temperatures (see Stewart et al., 2002). mRNA detected by RT-PCR in M. tuberculosis H37Rv under several in vitro growth conditions (oxidative stress and control) (See Akif et al., 2008). |
| 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). 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 |
