EC 6.2.1.36 Details

show Brenda entry

EC number

6.2.1.36

Accepted name

3-hydroxypropionyl-CoA synthase

Reaction

3-hydroxypropanoate + ATP + CoA = 3-hydroxypropanoyl-CoA + AMP + diphosphate

Other name(s)

3-hydroxypropionyl-CoA synthetase (AMP-forming), 3-hydroxypropionate—CoA ligase

Systematic name

hydroxypropanoate:CoA ligase (AMP-forming)

Comment

Catalyses a step in the 3-hydroxypropanoate/4-hydroxybutanoate cycle, an autotrophic CO₂ fixation pathway found in some thermoacidophilic archaea [1,2].The enzymes from Metallosphaera sedula and Sulfolobus tokodaii can also use propionate, acrylate, acetate, and butanoate as substrates [2], and are thus different from EC 6.2.1.17 (propionate—CoA ligase), which does not accept acetate or butanoate.
