Dehydrogenation of 3-hydroxy tetracosahexaenoyl-CoA 3-hydroxy tetracosahexaenoyl-CoA undergoes dehydrogenation to form 1-(3-oxo-6Z,9Z,12Z,15Z,18Z,21Z-tetracosahexaenoyl)-CoA, catalysed by DBP. DBP is a bifunctional enzyme, involved in the hydration of a variety of trans-2,3-dehydroacyl-CoA's but also mediating dehydrogenation of a variety of 3-hydroxyacyl-CoA's (Jiang et al. 1997).
