epithiospecifier protein | ESP, is a small protein of molecular weight 30 to 40 kDa, which co-occurs with myrosinase. ESP does not have thioglucosidase activity, but interacts with myrosinase to promote the transfer of sulfur from the S-glucose moiety of terminally unsaturated glucosinolates to the alkenyl moiety, resulting in the formation of epithionitriles. The presence of ferrous ions are essential for ESP function. | Brassica oleracea | |
