acyl-CoA (9+3)-desaturase

This microsomal enzyme introduces a cis double bond at position 12 of fatty-acyl-CoAs that contain a cis double bond at position 9. When acting on 19:1Δ10 fatty acyl-CoA the enzyme from the pathogenic protozoan Trypanosoma brucei introduces the new double bond at position 13, indicating that the new double bond is introduced three carbons from the existing cis double bond, towards the methyl-end of the fatty acid. Requires cytochrome b5 as the electron donor.
