Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
Br-
inhibition of mutant enzyme S402A between pH 3.5 and 4.5: concentrations greater than 0.2 mM inhibit, between pH 5.0 and 5.5: concentrations above 0.5 mM inhibit, between pH 6.0 and 6.3: 0.5 mM does not inhibit the mutant enzyme
Cl-
pH 4.1: mixed type inhibition with respect to H2O2, pH 3.1: competitive inhibition
hydrazine
uncompetitive; uncompetitive inhibition, inhibition constant: 0.3 mM
hydroxylamine
competitive and uncompetitive inhibition; inhibits rVCPO both competitively and uncompetitively. The competitive inhibition constant: 0.04 mM, uncompetitive inhibition 0.08 mM
NO3-
pH 5.5: competitive inhibition of the chlorination reaction with respect to chloride, uncompetitive with respect to H2O2
azide
uncompetitive; uncompetitive inhibition, inhibition constant: 50 nM
substitution of vanadate in the active site by phosphate leads to inactivation of the enzyme. Presence of H2O2 prevents inactivation by phosphate; substitution of vanadate in the active site by phosphate leads to inactivation. Presence of H2O2 prevents the inactivation
