EC number
1.14.19.16
Accepted name
linoleoyl-lipid Δ12 conjugase (11E,13Z-forming)
Reaction
a linoleoyl-[glycerolipid] + 2 ferrocytochrome b5 + O2 + 2 H+ = a (9Z,11E,13Z)-octadeca-9,11,13-trienoyl-[glycerolipid] + 2 ferricytochrome b5 + 2 H2O
Other name(s)
Fac (gene name)
Systematic name
linoleoyl-lipid,ferrocytochrome-b5:oxygen 11,14 allylic oxidase (11E,13Z-forming)
Comment
The enzyme, characterized from the plants Punica granatum (pomegranate) and Trichosanthes kirilowii (Mongolian snake-gourd), converts a single cis double bond at position 12 of linoleate incorporated into phosphatidylcholine into conjugated 11-trans and 13-cis double bonds. cf. EC 1.14.19.33, Δ12 acyl-lipid conjugase (11E,13E-forming).
