2.3.2.2 | glutathione + amino acid | Histoplasma capsulatum | Ggt1 initiates enzymatic breakdown of GSH by cleavage of the gamma-glutamyl bond and release of cysteinylglycine. Second, the thiol group of the released dipeptide reduces ferric to ferrous iron. A combination of kinetic properties of both reactions results in efficient iron reduction over a broad pH range | L-cysteinylglycine + 5-L-glutamyl-amino acid | - |
