Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
KCN
-
although 1 mM KCN completely inhibits hydroxylamine reduction, it does not inhibit the reduction of K3Fe(CN)6 and only decreases the rate of cytochrome c reduction by 12%
NAD+
-
NAD+ shows mixed product inhibition with respect to NADH and mixed or uncompetitive inhibition with respect to hydroxylamine
nitrite
-
nitrite decrease the rate of NADH-dependent reduction of cytochrome c by 77% and that of Fe(CN)63- by 90%
p-chloromercuribenzoate
-
the reduction of cytochrome c, K3Fe(CN)6 and hydroxylamine is completely inhibited (more than 99%) by 0.02 mM p-chloromercuribenzoate
-
dithiothreitol and EDTA have no evident effects on enzyme activity
-
