1.14.19.39	additional information	H6Cf0807 is an acetylenase, that produces a trans DELTA12 double bond, while H6Cf0745 is a classical FAD2 desaturase. The Cantharellus formosus FAD2 homologue H6Cf0745 expression results in the production of only 16:2 DELTA9,12 and 18:2 DELTA9,12 in recombinant yeast cells supplemented with 18:2 DELTA9c,12c. Expression ofH6Cf0807 results in the production of crepenynic acid, 18:1 DELTA9c,12a. No C16 acetylenic fatty acid is detected. Supplementation with 18:2 DELTA9c,12t, alpha-linolenic acid, 18:3 DELTA9,12,15, or gamma-linolenic acid, 18:3 DELTA6,9,12, does not result in the production of other fatty acids, overview
