FunctionPlays 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].
ProductProbable gamma-glutamyltranspeptidase precursor GgtB (gamma-glutamyltransferase) (glutamyl transpeptidase)
CommentsRv2394, (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).
