ID   1.14.19.2
DE   stearoyl-[acyl-carrier-protein] 9-desaturase.
AN   acyl-[acyl-carrier-protein] desaturase.
AN   stearyl-ACP desaturase.
AN   stearyl acyl carrier protein desaturase.
CA   2 H(+) + O2 + octadecanoyl-[ACP] + 2 reduced [2Fe-2S]-[ferredoxin] =
CA   (9Z)-octadecenoyl-[ACP] + 2 H2O + 2 oxidized [2Fe-2S]-[ferredoxin].
CC   -!- The enzyme is found in the lumen of plastids, where de novo
CC       biosynthesis of fatty acids occurs, and acts on freshly synthesized
CC       saturated fatty acids that are still linked to acyl-carrier protein.
CC   -!- The enzyme determines the position of the double bond by its distance
CC       from the carboxylic acid end of the fatty acid.
CC   -!- It also acts on palmitoyl-[acyl-carrier-protein].
CC   -!- Formerly EC 1.14.99.6.
