Reaction: a stearoyl-[acyl-carrier protein] + reduced acceptor + O2 = an oleoyl-[acyl-carrier protein] + acceptor + 2 H2O
Other name(s): stearyl acyl carrier protein desaturase; stearyl-ACP desaturase; acyl-[acyl-carrier-protein], hydrogen-donor:oxygen oxidoreductase
Systematic name: acyl-[acyl-carrier protein], hydrogen-donor:oxygen oxidoreductase
Comments: The enzyme from safflower is specific for stearoyl-[acyl-carrier protein]; that from Euglena acts on derivatives of a number of long-chain fatty acids. Requires ferredoxin.
