Characterization of Active Center of a Non-Heme Chloroperoxidase by X-Ray Absorption Fine Structure

XAFS studies on this non-heme chloroperoxidase reveal that its Fe core is in a saturated six-coordinate, octahedral environment with four planer N atoms and two axial S atoms. The active site is very similar to Fe porphyrine center in P450 oxidase, but the coordinated N atoms come from amino acids o...

Description
Summary:XAFS studies on this non-heme chloroperoxidase reveal that its Fe core is in a saturated six-coordinate, octahedral environment with four planer N atoms and two axial S atoms. The active site is very similar to Fe porphyrine center in P450 oxidase, but the coordinated N atoms come from amino acids of polypeptides or other molecules, but not porphyrin.
