1 Oxidative inactivation of brain ecto-5"-nucleotidase by thiols/Fe2+ system. Sulfhydryl Compounds 5'-nucleotidase Bos taurus
2 Overall, thiols, expressing more inhibitory effect on the activity of 5"-nucleotidase, were found to be more effective in potentiating the Fe2+-mediated inactivation. Sulfhydryl Compounds 5'-nucleotidase Bos taurus
3 Further, kinetic analyses indicate that Fe2+ and thiols inhibit the 5"-nucleotidase in a competitive or uncompetitive manner, respectively. Sulfhydryl Compounds 5'-nucleotidase Bos taurus
4 These results suggest that ecto-5"-nucleotidase from brain membrane is one of proteins susceptible to thiols/Fe2+-catalyzed oxidation, and the oxidative inactivation may be related to the selective association of Fe2+ and thiols to the enzyme molecule. Sulfhydryl Compounds 5'-nucleotidase Bos taurus
