KEGG   ENZYME: 1.14.19.13
Entry
EC 1.14.19.13               Enzyme                                 
Name
acyl-CoA 15-desaturase;
DES3 (gene name)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With oxidation of a pair of donors resulting in the reduction of O2 to two molecules of water
Sysname
acyl-CoA,reduced acceptor:oxygen oxidoreductase (15,16 cis-dehydrogenating)
Reaction(IUBMB)
(9Z,12Z)-hexadeca-9,12-dienoyl-CoA + reduced acceptor + O2 = (9Z,12Z,15Z)-hexadeca-9,12,15-trienoyl-CoA + acceptor + 2 H2O [RN:R11643]
Reaction(KEGG)
R11643
Substrate
(9Z,12Z)-hexadeca-9,12-dienoyl-CoA [CPD:C21000];
reduced acceptor [CPD:C00030];
O2 [CPD:C00007]
Product
(9Z,12Z,15Z)-hexadeca-9,12,15-trienoyl-CoA;
acceptor [CPD:C00028];
H2O [CPD:C00001]
Comment
The enzyme, characterized from the the plant Sorghum bicolor, is involved in the biosynthesis of sorgoleone, an allelopathic compound produced in root hair cells. The enzyme inserts a cis double bond at carbon 15. When acting on its natural substrate, (9Z,12Z)-hexadeca-9,12-dienoyl-CoA, it produces a product with a terminal double bond.
