acyl-lipid Delta(6)-desaturase
Delta(6)-desaturase
Reaction catalysed
  • (9Z,12Z,15Z)-octadecatrienoyl-containing glycerolipid + 2 Fe(II)-[cytochrome b5] + O2 + 2 H(+) = (6Z,9Z,12Z,15Z)-octadecatetraenoyl-containing glycerolipid + 2 Fe(III)-[cytochrome b5] + 2 H2O
  • a (9Z,12Z)-octadecadienoyl-containing glycerolipid + 2 Fe(II)-[cytochrome b5] + O2 + 2 H(+) = (6Z,9Z,12Z)-octadecatrienoyl-containing glycerolipid + 2 Fe(III)-[cytochrome b5] + 2 H2O
Comment(s)
  • The enzyme, characterized from the moss Physcomitrella patens and the plant Borago officinalis (borage), introduces a cis double bond at carbon 6 of several acyl-lipids that contain an existing Delta(9) cis double bond.
  • The enzyme contains a cytochrome b5 domain that acts as the electron donor for the active site of the desaturase.
