CC -!- FUNCTION: Converts stearoyl-ACP to oleoyl-ACP by introduction of a cis
CC double bond between carbons 9 and 10 of the acyl chain. Required for
CC the repression of the salicylic acid (SA) signaling pathway.
CC {ECO:0000250|UniProtKB:P22337}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 H(+) + O2 + octadecanoyl-[ACP] + 2 reduced [2Fe-2S]-
CC [ferredoxin] = (9Z)-octadecenoyl-[ACP] + 2 H2O + 2 oxidized [2Fe-2S]-
CC [ferredoxin]; Xref=Rhea:RHEA:11776, Rhea:RHEA-COMP:9656, Rhea:RHEA-
CC COMP:9924, Rhea:RHEA-COMP:10000, Rhea:RHEA-COMP:10001,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,

CC ChEBI:CHEBI:78783; EC=1.14.19.2;
CC Evidence={ECO:0000250|UniProtKB:P22337};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000250|UniProtKB:P22337};
CC Note=Binds 2 Fe(2+) ions per subunit. {ECO:0000250|UniProtKB:P22337};
CC -!- PATHWAY: Lipid metabolism; fatty acid metabolism.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P22337}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the fatty acid desaturase type 2 family.
CC {ECO:0000305}.
