CC -!- FUNCTION: Stearoyl-CoA desaturase that utilizes O(2) and electrons from
CC reduced cytochrome b5 to introduce the first double bond into saturated
CC fatty acyl-CoA substrates. {ECO:0000256|PIRNR:PIRNR000345}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 Fe(II)-[cytochrome b5] + 2 H(+) + O2 + octadecanoyl-CoA =
CC (9Z)-octadecenoyl-CoA + 2 Fe(III)-[cytochrome b5] + 2 H2O;
CC Xref=Rhea:RHEA:19721, Rhea:RHEA-COMP:10438, Rhea:RHEA-COMP:10439,

CC ChEBI:CHEBI:57394; EC=1.14.19.1;
CC Evidence={ECO:0000256|PIRNR:PIRNR000345};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000256|PIRNR:PIRNR000345};
CC Note=Expected to bind 2 Fe(2+) ions per subunit.
CC {ECO:0000256|PIRNR:PIRNR000345};
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}.
CC -!- DOMAIN: The histidine box domains are involved in binding the catalytic
CC metal ions. {ECO:0000256|RuleBase:RU000581}.
CC -!- SIMILARITY: Belongs to the fatty acid desaturase type 1 family.
