Redox and chemical activities of the hemes in the sulfur oxidation pathway enzyme SoxAX.

BACKGROUND: SoxAX enzymes initiate microbial oxidation of reduced inorganic sulfur compounds. Their catalytic mechanism is unknown. RESULTS: Cyanide displaces the CysS(-) ligand to the active site heme following reduction by S(2)O(4)(2-) but not Eu(II). CONCLUSION: An active site heme ligand become...
