ENZYME - 1.14.19.33 Delta(12) acyl-lipid conjugase (11E,13E-forming)

Accepted Name
Delta(12) acyl-lipid conjugase (11E,13E-forming)
Alternative Name(s)
fatty acid Delta(12)-conjugase
Reaction catalysed
  • a (9Z,12Z)-octadecadienoyl-containing glycerolipid + 2 Fe(II)-[cytochrome b5] + O2 + 2 H(+) = a (9Z,11E,13E)-octadecatrienoyl-containing glycerolipid + 2 Fe(III)-[cytochrome b5] + 2 H2O
  • (9Z,12Z,15Z)-octadecatrienoyl-containing glycerolipid + 2 Fe(II)-[cytochrome b5] + O2 + 2 H(+) = a (9Z,11E,13E,15Z)-octadecatetraenoyl-containing glycerolipid + 2 Fe(III)-[cytochrome b5] + 2 H2O
Comment(s)
  • The enzyme, characterized from the plants Impatiens balsamina, Momordica charantia (bitter gourd) and Vernicia fordii (tung tree), converts a single cis double bond at carbon 12 to two conjugated trans bonds at positions 11 and 13.
  • The enzyme from Vernicia fordii can also act as a 12(E) desaturase when acting on the monounsaturated fatty acids oleate and palmitoleate. cf. EC 1.14.19.16.
