Enzyme Information

4-hydroxybutanoyl-CoA dehydratase.
based on mapping to UniProt P55792
4-hydroxybutanoyl-CoA = (E)-but-2-enoyl-CoA + H(2)O.
-!- The enzyme has been characterized from several microorganisms, including Clostridium kluyveri, where it participates in succinate fermentation, Clostridium aminobutyricum, where it participates in 4-aminobutyrate degradation, and Metallosphaera sedula, where it participates in the 3-hydroxypropionate/4-hydroxybutyrate cycle, an autotrophic CO(2) fixation pathway found in some thermoacidophilic archaea.

| 5.3.3.3 |
Vinylacetyl-CoA Delta-isomerase.
based on mapping to UniProt P55792
Vinylacetyl-CoA = (E)-but-2-enoyl-CoA.
-!- Also acts on 3-methyl-vinylacetyl-CoA.
