| swapping metals in fe- and mn-dependent dioxygenases: evidence for oxygen activation without a change in metal redox state. | biological o(2) activation often occurs after binding to a reduced metal [e.g., m(ii)] in an enzyme active site. subsequent m(ii)-to-o(2) electron transfer results in a reactive m(iii)-superoxo species. for the extradiol aromatic ring-cleaving dioxygenases, we have proposed a different model where an electron is transferred from substrate to o(2) via the m(ii) center to which they are both bound, thereby obviating the need for an integral change in metal redox state. this model is tested by usin ... | 2008 | 18492808 |
