WebNov 1, 2008 · Both epithiospecifier protein and nitrile‐specifier protein appear to be true enzymes rather than allosteric cofactors of myrosinases, based on their substrate and product specificities and the fact that the proportion of glucosinolates hydrolysed to nitriles does not remain constant whenMyrosinase activity varies.

WebDec 1, 2001 · Called the epithiospecifier protein (ESP), its presence during the hydrolysis of alkenyl glucosinolates leads to the formation of epithionitriles instead of isothiocyanates by transfer of the sulfur atom from the basic glucosinolate backbone to the terminal alkene residue of the side chain ( Figure 1 ). WebSep 16, 2016 · They are epithiospecifier proteins (ESPs), thiocyanate forming proteins (TFPs), and nitrile-specifier proteins (NSPs) [1], [4], [14], [15]. ESP was first isolated from Crambe abyssinica and named by Tookey et al., for its activity in promoting epithionitrile formation in the presence of glucosinolates and myrosinases.
