Phenoxazinone Synthase

Two tetranuclear copper complexes with a Cu4O4 cubane core exhibiting phenoxazinone synthase like activity are reported.

To be structurally well-defined or not to be, that is not the question for iron(III)–poly(4-Vinylpyridine-co-acrylamide) to exhibit catechol dioxygenase activity!
