摘要：

17O effects have been observed on the MoV EPR signals from sulfite oxidase, xanthine dehydrogenase, and MoO(SC6H5)4-. The results point to the presence of a rapidly exchangeable oxygen ligand in the molybdenum coordination sphere of the enzymes. Average splittings were on the order of 10 gauss for the enzymes, but only about 2 gauss for MoO(SC6H5)4-. © 1979.
