Function and Biology Details

Reactions catalysed:
A (3R)-3-hydroxyacyl-[acyl-carrier protein] = a trans-2-enoyl-[acyl-carrier protein] + H(2)O
Acyl-[acyl-carrier-protein] + malonyl-[acyl-carrier-protein] = 3-oxoacyl-[acyl-carrier-protein] + CO(2) + [acyl-carrier-protein]
Acetyl-CoA + [acyl-carrier-protein] = CoA + acetyl-[acyl-carrier-protein]
Malonyl-CoA + an [acyl-carrier-protein] = CoA + a malonyl-[acyl-carrier-protein]
Acetyl-CoA + n malonyl-CoA + 2n NADPH = a long-chain fatty acid + (n+1) CoA + n CO(2) + 2n NADP(+)
(3R)-3-hydroxyacyl-[acyl-carrier-protein] + NADP(+) = 3-oxoacyl-[acyl-carrier-protein] + NADPH
Oleoyl-[acyl-carrier-protein] + H(2)O = [acyl-carrier-protein] + oleate
An acyl-[acyl-carrier protein] + NADP(+) = a trans-2,3-dehydroacyl-[acyl-carrier protein] + NADPH
