This enzyme, found in cyanobacteria, reduces a long-chain (mainly C16 or C18) fatty acyl ACP ester to its corresponding fatty aldehyde, releasing the acyl carrier protein (ACP). NADPH or NADH is the reductant for this reaction. This enzyme may be distantly related to the short-chain dehydrogenase or reductase (SDR) family (pfam00106). The purpose of this reaction is in the first step of alkane biosynthesis (GenProp0942). [Central intermediary metabolism, Other]
