Activating Compound

EC Number Activating Compound Comment Organism Structure
1.14.19.17 myristic acid the activity of wild-type isoform DES1 is linearly increased in the presence of increased concentrations of myristic acid. The dihydroceramide DELTA4-desaturase activity of the myristoylable enzyme is reproducibly and significantly higher than the unmyristoylated enzyme Rattus norvegicus
