Bridging oxo group
WebSep 5, 2014 · The enzyme contains a complex active-site cofactor comprising two antiferromagnetically coupled ferric iron ions (Fe 3+ ), three calcium ions (Ca 2+ ), and an oxo group bridging three of the metal ions. Notably, the main part of the cofactor resembles synthetic oxide-centered triangular metal complexes. WebThis chemistry already represents a crude functional model for CcO, since O2 has been reduced to the oxidation state level of water; isotope labeling studies indicate the bridging oxo group in (4) comes from O2. Interestingly, the acid-base reaction of equimolar amounts of (5), (6), and Et3N gives the same complex, (4).
