A modo de control para el ensayo para la actividad ∆ 15-desaturasa, las levaduras se transforman con el vector vacío pYES, se carga el ácido graso 18:2 n-6 y el perfil de ácidos grasos se analiza (Figura 2A). En comparación, el 5 ácido graso adicional 18:3 n-3 se puede observar en levaduras que expresan las desaturasas d15Des (Ch) y d15Des(Cy) (Figura 2B, 2C). Estas desaturasas que se han ensayado, por lo tanto, tienen actividad ∆15-desaturasa.
Ejemplo 5: Producción de Plantas transgénicas para la producción de ácidos grasos poliinsaturados de cadena larga
Para producir ácidos grasos poliinsaturados de cadena larga en plantas, diversos genes de la ruta metabólica se combinan en un vector binario. Para producir el ácido graso ácido eicosapentaenoico (20:5∆5,8,11,14,17), se 10 combinan los genes como se describe en la Tabla 5. Análogamente, Los genes como se describe en la Tabla 6 se combinan para producir el ácido graso ácido docosahexaenoico (22:06∆4,7,10,13,16,19).
