protoviolaceinate [CPD:C21134];
NADH [CPD:C00004];
NADPH [CPD:C00005];
O2 [CPD:C00007];
protodeoxyviolaceinate [CPD:C21131]

The enzyme, characterized from the bacterium Chromobacterium violaceum, participates in the biosynthesis of the violet pigment violacein. The products, violaceinate and deoxyviolaceinate, undergo non-enzymic autooxidation into violacein and deoxyviolacein, respectively.
