==Reference==

[https://www.uniprot.org/uniprot/HDVD_CLOAM HDVD_CLOAM] Catalyzes the reversible conversion of 4-hydroxybutyryl-CoA to crotonyl-CoA. The mechanism of the reaction seems to go through three steps: (1) the FAD-dependent oxidation of 4-hydroxybutyryl-CoA to 4-hydroxycrotonyl-CoA; (2) the hydroxyl group is substituted by a hydride derived from the now reduced FAD in an SN2' reaction leading to vinylacetyl-CoA; (3) isomerization to yield crotonyl-CoA.
