Display the reaction diagram Show all sequences 1.14.14.B10more enzyme binds and degrades heme in a reaction that releases carbon monoxide. Initial intermediates of the reaction of ChuS with hydrogen peroxide, i.e. a ferrous keto pi neutral radical and ferric verdoheme, are in common with heme oxygenases, while a further reaction step, involving the cleavage of the porphyrin ring at adjacent meso-carbons, results in the release of hematinic acid, a tripyrrole product and non-heme iron in the ferric oxidation state Escherichia coli ? - ?
