Gene Rv2394
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Plays a key role in the gamma-glutamyl cycle, a pathway for the synthesis and degradation of glutathione [catalytic activity: 5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl-amino acid]. |
| Product | Probable gamma-glutamyltranspeptidase precursor GgtB (gamma-glutamyltransferase) (glutamyl transpeptidase) |
| Comments | Rv2394, (MTCY253.27c), len: 643 aa. Probable ggtB, gamma-glutamyltranspeptidase precursor, similar to many e.g. Q9KVF2|VC0194 from Vibrio cholerae (588 aa), FASTA scores: opt: 943, E(): 7.5e-47, (40.0% identity in 597 aa overlap); O69935|SC3C8.26 from Streptomyces coelicolor (603 aa), FASTA scores: opt: 822, E(): 7.2e-40, (33.6% identity in 622 aa overlap); P54422|GGT_BACSU from Bacillus subtilis (587 aa) FASTA scores: opt: 491, E(): 8.2e-21, (33.4% identity in 574 aa overlap); etc. Has potential signal peptide and appropriately positioned prokaryotic lipoprotein attachment site (PS00013). |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003).
