Enzyme Information
| 1.14.19.2 |
Stearoyl-[acyl-carrier-protein] 9-desaturase.
based on mapping to UniProt P22337
Stearoyl-[acyl-carrier protein] + 2 reduced ferredoxin [iron-sulfur] cluster + O(2) + 2 H(+) = oleoyl-[acyl-carrier protein] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O.
-!- The enzyme is found in the lumen of plastids, where de novo biosynthesis of fatty acids occurs, and acts on freshly synthesized saturated fatty acids that are still linked to acyl-carrier protein. -!- The enzyme determines the position of the double bond by its distance from the carboxylic acid end of the fatty acid. -!- It also acts on palmitoyl-[acyl-carrier-protein]. -!- Formerly EC 1.14.99.6.
