Sulfhydryl Compounds 56-62 5'-nucleotidase Bos taurus 32-52 11071366-10 2000 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 9-15 5'-nucleotidase Bos taurus 70-85 11071366-11 2000 Further, kinetic analyses indicate that Fe2+ and thiols inhibit the 5"-nucleotidase in a competitive or uncompetitive manner, respectively. Sulfhydryl Compounds 49-55 5'-nucleotidase Bos taurus 68-83 11071366-12 2000 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 102-108 5'-nucleotidase Bos taurus 27-47 11071366-12 2000 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.
