| EC Number | 3.4.19.16 |
| Enzyme Function | FUNCTION: Involved in glucosinolate biosynthesis. Hydrolyzes the gamma-glutamyl peptide bond of several glutathione (GSH) conjugates to produce Cys-Gly conjugates related to glucosinolates. The gamma-Glu-Cys-Gly-GSH conjugates are the sulfur-donating molecule in glucosinolate biosynthesis. {ECO:0000250|UniProtKB:Q9M0A7}. |
