KEGG   ENZYME: 1.17.9.2
Entry
EC 1.17.9.2                 Enzyme                                 
Name
(+)-pinoresinol hydroxylase;
pinoresinol alpha-hydroxylase;
pinAB (gene names)
Class
Oxidoreductases;
Acting on CH or CH2 groups;
With a copper protein as acceptor
Sysname
(+)-pinoresinol:azurin oxidoreductase
Reaction(IUBMB)
(+)-pinoresinol + 2 oxidized azurin + H2O = (+)-6-hydroxypinoresinol + 2 reduced azurin + 2 H+ [RN:R12653]
Reaction(KEGG)
R12653
Substrate
(+)-pinoresinol [CPD:C05366];
oxidized azurin [CPD:C05357];
H2O [CPD:C00001]
Product
(+)-6-hydroxypinoresinol [CPD:C22302];
reduced azurin [CPD:C05358];
H+ [CPD:C00080]
Comment
Contains FAD. This enzyme, characterized from the bacterium Pseudomonas sp. SG-MS2, catalyses the incorporation of an oxygen atom originating from a water molecule into position C-6 of the lignan (+)-pinoresinol. The enzyme consists of a flavoprotein subunit and a c-type cytochrome subunit. Electrons that originate in the substrate are transferred via the FAD cofactor and the cytochrome subunit to the blue-copper protein azurin.
