1.14.15.21	Cd2+	inhibition by interaction with a cysteine residue of the protein that is important for the enzyme activity	52	
1.14.15.21	Cd2+	inhibition by interaction with a cysteine residue of the protein that is important for the enzyme activity, inhibition by cadmium ions is reversible by Zn2+ ions	52	
1.14.15.21	diphenylene iodonium chloride	IC50: 0.0023 mM	9532	
1.14.15.21	additional information	no inhibition by Cd2+	2	
1.14.15.21	additional information	no effect of sugars and amino sugars on violaxanthin de-epoxidase is observed, but epoxidation of zeaxanthin to violaxanthin is inhibited, incubation with amino sugars under a 6 d photoperiod enhances the inhibitory effect, zeaxanthin epoxidation is completely inhibited under such conditions, overview	2	
1.14.15.21	additional information	chilling stress under low irradiance and high light increase the de-epoxidation of xanthophyll cycle pigments, transgenic enzyme-overexpressing plants show enhanced PSII photoinhibition to high light and chilling stress	2	
1.14.15.21	NaBr	there is a decrease of enzyme activity to 21% of the activity of control thylakoids when incubated once with 2 M NaBr. A second treatment with 2 M NaBr leads to an almost complete inhibition of enzyme activity	2348	
1.14.15.21	octylglucoside	complete inhibition at 30 mM	4275
