Predicted to enable several functions, including dodecenoyl-CoA delta-isomerase activity; enoyl-CoA hydratase activity; and long-chain-3-hydroxyacyl-CoA dehydrogenase activity. Acts upstream of or within fatty acid beta-oxidation. Located in mitochondrion. Is expressed in several structures, including alimentary system; brown fat; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in Fanconi renotubular syndrome 3. Orthologous to human EHHADH (enoyl-CoA hydratase and 3-hydroxyacyl CoA dehydrogenase).
