CO does not inhibit the enzyme 2 1.13.11.60 additional information catalysis declines due to suicide inactivation; catalysis declines due to suicide inactivation. Following column chromatography, e.g. ion exchange or zinc-affinity chromatography, hydroperoxide isomerase activity is often decreased and sometimes even undetectable by TLC, whereas 8-dioxygenase activity is always present. However, storage of the enzyme for a few days on ice often restores the hydroperoxide isomerase and appeares to increase the 7,8-linoleate diol synthase activity as well 2 1.13.11.60 additional information GSH (1 mM), GSSG (1 mM), EDTA (1 or 10 mM), EGTA (1 or 10 mM) and H202 (10 mM) are without effect on the 8R-dioxygenase 2 1.13.11.60 additional information sorbitol (0.75 M, 14%), glycerol (15%) and ethylene glycol (25%) do not inhibit the enzyme 2 1.13.11.60 additional information suicide inactivation, activity falls to zero within a few min although substrates were available in sufficient amounts 2 1.13.11.60 N-tosyl-L-phenylalanyl chloromethyl ketone 1 mM, over 70% inhibition 13071 1.13.11.60 N-[(E)-3-(3-phenoxyphenyl)prop-2-enyl]acetohydroxamic acid i.e. BW A4C, more than 90% inhibition at 0.01 mM, about 50% inhibition at 0.001 mM 19470 1.13.11.60 N-[(E)-3-(3-phenoxyphenyl)prop-2-enyl]acetohydroxamic acid i.e. BW A4C 19470 1.13.11.60 nordihydroguaiaretic acid - 926 1.13.11.60 paracetamol 0.2 mM, over 80% inhibition 7459 1.13.11.60 paracetamol 0.03 mM, 44% inhibition 7459 1.13.11.60 phenylmethanesulfonyl fluoride 0.2 mM, inhibits the 8R-dioxygenase enzyme by over 85% 827 1.13.11.60 polyoxyethylene-10 lauryl ether 0.5%, inactivation 165831 1.13.11.60 sodium deoxycholate 0.5%, inactivation 549 1.13.11.60 Tetranitromethane 0.4 mM, 50% inhibition 1453 1.13.11.60 Triton X-100 0.5%, inactivation 61 1.13.11.60 Tween 20 0.5%, inactivation 555 1.13.11.60 Tween 80 0.5%, inactivation 514 1.13.11.60 Urea 1-4 M 116 1.13.11.60 zileuton - 3136
