S. ALBA MYROSINASE IN COMPLEX WITH CARBA-GLUCOTROPAEOLIN

Overview

Myrosinase, a thioglucoside glucohydrolase, is the only enzyme able to, hydrolyse glucosinolates, a unique family of molecules bearing an anomeric, O-sulfated thiohydroximate function. Non-hydrolysable myrosinase, inhibitors have been devised and studied for their biological interaction., Diverse modifications of the O-sulfate moiety did not result in a, significant inhibitory effect, whereas replacing the D-glucopyrano residue, by its carba-analogue allowed inhibition to take place. X-Ray experiments, carried out after soaking allowed for the first time inclusion of a, non-hydrolysable inhibitor inside the enzymatic pocket. Structural tuning, of the aglycon part in its pocket is being used as a guide for the, development of simplified and more potent inhibitors.
