EC Number | General Information | Comment | Organism |
---|---|---|---|
1.14.19.14 | physiological function | enzyme expression is occasionally associated with dramatic changes in morphology of the endoplasmic reticulum | Vernicia fordii |
1.14.19.33 | evolution | tung FADX is grouped with DELTA12 fatty acid desaturases and hydroxylases rather than conjugases, which is consistent with its desaturase activity | Vernicia fordii |
1.14.19.33 | additional information | incubation of yeast cells expressing FADX with exogenously supplied palmitoleicacid leads to substantial incorporation of thisfatty acid into yeast cells, accounting for approximately79% of total fatty acids. Oleic acid is reduced to only 3% under these growth conditions | Vernicia fordii |
1.14.19.33 | physiological function | FADX converts linoleic acid into alpha-eleostearic acid. in the plant seed oil | Vernicia fordii |
1.14.19.34 | evolution | the enzyme belongs to the FAD2 enzyme family | Vernicia fordii |
1.14.19.34 | physiological function | FAD2 converts oleic acid into linoleic acid in the plant seed oil | Vernicia fordii |
