---|---|---|
E47A | the electronic absorption band corresponding to the oxidized active site exhibits a pH-dependent alkaline transition changing from ca. 644 to 560 nm as the pH increases and with an apparent pKa of 9.0 in wild-type. In mutant E47A, this pKa shifts to 6.7 | Desulfarculus baarsii |
K48I | the electronic absorption band corresponding to the oxidized active site exhibits a pH-dependent alkaline transition changing from ca. 644 to 560 nm as the pH increases and with an apparent pKa of 9.0 in wild-type. In mutant K48I, this pKa shifts to 7.6 | Desulfarculus baarsii |

Iron | non-heme iron in square-pyramidal [His4Cys] coordination. At basic pH a high-spin Fe3+-OH species is formed at the active site, which upon protonation results in a water molecule in the active site | Desulfarculus baarsii |
