Identification of an Activity Selector for the Nitroso‐Forming Activity in Bacterial Type‐III Copper Enzymes

open access: yesAngewandte Chemie International Edition, EarlyView.
Small but crucial difference: Type‐III copper enzymes, like tyrosinase (TYR) and o‐aminophenol oxidase (AO), catalyze the oxidation of o‐aminophenols (AP) to quinone imines. Unlike TYR, AO can further oxidize AP to nitrosophenols. This nitroso‐forming activity is controlled by a key amino acid near the Cu(A) ion.
