H+ [CPD:C00080];
dec-9-enoyl-[acyl-carrier protein] [CPD:C22343]

The enzyme, characterized from the bacterium Teredinibacter turnerae, is specific for decanoyl-[acyl-carrier protein]. Activity is maximal when decanoate is loaded onto a dedicated acyl-carrier protein (TtuC), which is encoded by a gene in the same operon.
