CRYSTAL STRUCTURE OF OXALATE DECARBOXYLASE

Overview

Oxalate decarboxylase (EC 4.1.1.2) catalyzes the conversion of oxalate to, formate and carbon dioxide and utilizes dioxygen as a cofactor. By, contrast, the evolutionarily related oxalate oxidase (EC 1.2.3.4) converts, oxalate and dioxygen to carbon dioxide and hydrogen peroxide. Divergent, free radical catalytic mechanisms have been proposed for these enzymes, that involve the requirement of an active site proton donor in the, decarboxylase but not the oxidase reaction. The oxidase possesses only one, domain and manganese binding site per subunit, while the decarboxylase has, two domains and two manganese sites per subunit. A structure of the, decarboxylase together with a limited mutagenesis study has recently been, interpreted as evidence that the C-terminal domain manganese binding ... [(full description)]
