1.11.2.2	ascorbic acid	converts inactive myeloperoxidase compound II into active myeloperoxidase	711274	
1.11.2.2	betanin	low micromolar betanin concentrations enhance the chlorination activity of MPO at pH 7.0, increasing the betanin concentration up to 0.006 mM dramatically increases the chlorination rate of monochlorodimedon	711064	
1.11.2.2	chloride	in the presence of 100 mM NaCl the catalytic efficiency of MPO increases 3-4fold whatever the sulfide considered, the rate of 4-tolyl methyl sulphide oxidation enhancement is about 8fold at 120 mM NaCl	711125	
1.11.2.2	D-penicillamine	addition of D-penicillamine significantly enhances the rate of chloroacetonitrile oxidation and cyanide release by the myeloperoxidase/H2O2/Cl- system (17.2% increase at 5 mM)	713543	
1.11.2.2	ferrocyanide	converts inactive myeloperoxidase compound II into active myeloperoxidase	711274	
1.11.2.2	glutathione	addition of glutathione significantly enhances the rate of chloroacetonitrile oxidation and cyanide release by the myeloperoxidase/H2O2/Cl- system (24% increase at 5 mM)	713543	
1.11.2.2	indicaxanthin	at neutral pH and depending on their concentration, indicaxanthin can exhibit a stimulating and inhibitory effect on the chlorination activity of MPO	711064	
1.11.2.2	L-cysteine	addition of L-cysteine significantly enhances the rate of chloroacetonitrile oxidation and cyanide release by the myeloperoxidase/H2O2/Cl- system (45.4% increase at 5 mM)	713543
