Gene Rv3704c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in glutathione biosynthesis (at the first step) [catalytic activity: ATP + L-glutamate + L-cysteine = ADP + orthophosphate + gamma-L-glutamyl-L-cysteine]. |
| Product | Glutamate--cysteine ligase GshA (gamma-glutamylcysteine synthetase) (gamma-ECS) (GCS) (gamma-glutamyl-L-cysteine synthetase) |
| Comments | Rv3704c, (MTV025.052c), len: 432 aa. Possible gshA, glutamate--cysteine ligase, similar to many e.g. Q9A2Z2|CC3414 glutamate--cysteine ligase from Caulobacter crescentus (453 aa), FASTA scores: opt: 404, E(): 5.9e-17, (30.45% identity in 312 aa overlap); Q9SEH0|GSH1 gamma-glutamylcysteinyl synthetase precursor from Pisum sativum (Garden pea) (499 aa), FASTA scores: opt: 400, E(): 1.1e-16, (26.4% identity in 439 aa overlap); Q9RH09|GSH gamma-glutamylcysteine synthetase from Zymomonas mobilis (462 aa), FASTA scores: opt: 397, E(): 1.6e-16, (28.95% identity in 304 aa overlap); P46309|GSH1_ARATH|GSH1|AT4G23100|F7H19.290 glutamate--cysteine ligase from Arabidopsis thaliana (Mouse-ear cress) (522 aa), FASTA scores: opt: 395, E(): 2.3e-16, (27.25% identity in 385 aa overlap); etc. But note that this putative protein is also similar to Q9JMV4|GSHA putative glutathione synthetase (fragment) from Bradyrhizobium japonicum (460 aa), FASTA scores: opt: 498, E(): 1.3e-22, (33.35% identity in 333 aa overlap) (no significant publications found (August 2001)). Nucleotide position 4147070 in the genome sequence has been corrected, A:G resulting in L373L. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| 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 |
