Function and Biology Details

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