Reaction

EC Number Reaction Comment Organism Reaction ID
1.14.19.1 stearoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = oleoyl-CoA + 2 ferricytochrome b5 + 2 H2O increase of activity induced by cold is preceded by the activation of latent desaturase, probably by a posttranslational mechanism. Amounts of desaturase transcript are increased as a result of cold-induced gene transcription Cyprinus carpio
