DE   acyl-[acyl-carrier-protein] 6-desaturase.
CA   2 H(+) + hexadecanoyl-[ACP] + O2 + 2 reduced [2Fe-2S]-[ferredoxin] =
CA   (6Z)-hexadecenoyl-[ACP] + 2 H2O + 2 oxidized [2Fe-2S]-[ferredoxin].
CC   -!- The enzyme, characterized from the endosperm of the plant Thunbergia
CC       alata (black-eyed Susan vine), introduces a cis double bond at carbon
CC       6 of several saturated acyl-[acyl-carrier protein]s.
CC   -!- It is most active with palmitoyl-[acyl-carrier protein] (16:0),
CC       but can also act on myristoyl-[acyl-carrier protein] (14:0) and
CC       stearoyl-[acyl-carrier protein] (18:0).
CC   -!- The position of the double bond is determined by its distance from
CC       the carboxyl end of the fatty acid.
