KEGG   ENZYME: 1.14.12.25
Entry
EC 1.14.12.25               Enzyme                                 

Name
p-cumate 2,3-dioxygenase
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and incorporation of two atoms of oxygen into the other donor
Sysname
4-isopropylbenzoate:oxygen 2,3-oxidoreductase
Reaction(IUBMB)
p-cumate + NADH + H+ + O2 = (2R,3S)-2,3-dihydroxy-2,3-dihydro-p-cumate + NAD+ [RN:R05247]
Reaction(KEGG)
R05247
Substrate
p-cumate [CPD:C06578];
NADH [CPD:C00004];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
(2R,3S)-2,3-dihydroxy-2,3-dihydro-p-cumate [CPD:C06579];
NAD+ [CPD:C00003]
Comment
The enzyme, characterized from several Pseudomonas strains, is involved in the degradation of p-cymene and p-cumate. It comprises four components: a ferredoxin, a ferredoxin reductase, and two subunits of a catalytic component. The enzyme can also act on indole, transforming it to the water-insoluble blue dye indigo.
