IntEnz Enzyme Nomenclature
EC 4.2.1.116

Names

Accepted name:
3-hydroxypropionyl-CoA dehydratase
Other names:
3-hydroxypropionyl-CoA hydro-lyase
3-hydroxypropanoate-CoA dehydratase
Systematic name:
3-hydroxypropanoate-CoA hydro-lyase

Reactions

Comments:

Catalyses a step in the 3-hydroxypropanoate/4-hydroxybutyrate cycle, an autotrophic CO2 fixation pathway found in some thermoacidophilic archaea [1]. The enzyme from Metallosphaera sedula acts nearly equally as well on (S)-3-hydroxybutanoyl-CoA but not (R)-3-hydroxybutanoyl-CoA [2].
