Name
violacein synthase;
proviolaceinate monooxygenase;
vioC (gene name)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor
BRITE hierarchy
Sysname
protoviolaceinate,NAD(P)H:O2 oxidoreductase
Reaction(IUBMB)
(1) protoviolaceinate + NAD(P)H + O2 = violaceinate + NAD(P)+ + H2O [RN:R11135 R11373];
(2) protodeoxyviolaceinate + NAD(P)H + O2 = deoxyviolaceinate + NAD(P)+ + H2O [RN:R11132 R11374]
Reaction(KEGG)
Substrate
protoviolaceinate [CPD:C21134];
NADH [CPD:C00004];
NADPH [CPD:C00005];
O2 [CPD:C00007];
protodeoxyviolaceinate [CPD:C21131]
Product
violaceinate [CPD:C21135];
NAD+ [CPD:C00003];
NADP+ [CPD:C00006];
H2O [CPD:C00001];
deoxyviolaceinate [CPD:C21132]
Comment
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.
