Reaction(IUBMB)
4-hydroxybutanoyl-CoA = (E)-but-2-enoyl-CoA + H2O [RN:

Product
Comment
Contains FAD and a [4Fe-4S] iron-sulfur cluster. The enzyme has been characterized from several microorganisms, including Clostridium kluyveri, where it participates in succinate fermentation [1,2], Clostridium aminobutyricum, where it participates in 4-aminobutyrate degradation [3,4], and Metallosphaera sedula, where it participates in the 3-hydroxypropionate/4-hydroxybutyrate cycle, an autotrophic CO2 fixation pathway found in some thermoacidophilic archaea [5].
