1.11.1.16 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) substrate inhibition 857 1.11.1.16 bovine pancreatic RNase competitive to oxidation of veratryl alcohol, non-competitive to oxidation of Mn2+ 58740 1.11.1.16 Co2+ 5 mM, 80% of initial activity 23 1.11.1.16 Cu2+ 5 mM, 18% of initial activity 19 1.11.1.16 DMSO 50% inhibition at 20%, 90% inhibition at 30%, pH 5.0, 25°C 896 1.11.1.16 Fe2+ 5 mM, 11% of initial activity 25 1.11.1.16 H2O2 6.4 mM, 5% loss of activity 22 1.11.1.16 H2O2 inhibitory in the absence of substrate 22 1.11.1.16 Mg2+ 5 mM, 85% of initial activity 6 1.11.1.16 Mn2+ above 0.1 mM, severe inhibition of oxidation of veratryl alcohol 11 1.11.1.16 N-bromosuccinimide modification of tryptophan residues by N-bromosuccinimide drastically reduces the Mn(II)-independent activity and dye decoloration, while Mn(II)-dependent activity is maintained. Effect is not reversed by addition of mediators 208 1.11.1.16 NaOCl the heme iron directly reacts with NaOCl. The heme reduces NaOCl toxicity towards Mb side-chains. The oxidized (Fe3+) form of Mb (metMB) peroxidase activity is significantly decreased after incubation with NaOCl and NaCN, but not with NaOCl alone 45761 1.11.1.16 Tween-80 80% inhibition at 5%, pH 5.0, 25°C 2672
