Complex I assembly factor ACAD9, mitochondrial (ACAD9)

Required for mitochondrial complex I assembly (PubMed:20816094, PubMed:24158852). Has a dehydrogenase activity on palmitoyl-CoA (C16:0) and stearoyl-CoA (C18:0).

It is three times more active on palmitoyl-CoA than on stearoyl-CoA. However, it does not play a main role in long-chain fatty acid oxidation in vivo (PubMed:20816094, PubMed:24158852).
