1.23.5.1 | Cys |
2.7 mM, 50% inhibition |
|
1.23.5.1 | dithiothreitol |
0.055 mM, 50% inhibition. The rate of conversion of violaxanthin to antheraxanthin is relatively unchanged whereas the conversion of antheraxanthin to zeaxanthin is 50-80% inhibited |

1.23.5.1 | mercaptoethanol |
0.68 mM, 50% inhibition |
|
1.23.5.1 | more |
no inhibitory effect by 10 mM Zn2+ and 10 mM Cd2+ |
|
1.23.5.1 | more |
no inhibition by glucose, glucosamine, galactose, galactosamine, mannose and mannosamine at a concentration of 0.5% |
|
1.23.5.1 | more |
replacement of monogalactosyldiacylglycerol with digalactosyldiacylglycerol or phosphatidylcholine (PC) in the assay medium results in a strong inhibition of xanthophyll cycle pigments, violaxanthin and diadinoxanthin de-epoxidation. VDE and DDE activity depends not on the chemical character of lipids but on the kind of structure they form in water environment |
|
1.23.5.1 | o-phenanthroline |
0.025 mM, 50% inhibition. The rate of conversion of violaxanthin to antheraxanthin is relatively unchanged whereas the conversion of antheraxanthin to zeaxanthin is 50-80% inhibited |
|
1.23.5.1 | pepstatin |
50% inhibition at 0.12 mM, reversible, protonation-induced structural change of the enzyme |
|
1.23.5.1 | pepstatin A |
