Compound as reactive (3)

4-hydroxybutanoyl-CoA + oxygen → hydrogen peroxide + 4-hydroxycrotonyl-CoA

4-hydroxybutanoyl-CoA → H₂O + crotonyl-CoA

4-hydroxybutanoyl-CoA → vinylacetyl-CoA + H₂O

Compound as product (3)

acetyl-CoA + 4-hydroxybutanoate → acetate + 4-hydroxybutanoyl-CoA

coenzyme A + ATP + 4-hydroxybutanoate → 4-hydroxybutanoyl-CoA + diphosphate + AMP

coenzyme A + ATP + 4-hydroxybutanoate → 4-hydroxybutanoyl-CoA + phosphate + ADP

Reversible reaction (1)

NAD(P)H + H⁺ + 4-hydroxybutanoyl-CoA ↔ coenzyme A + NAD(P)+ + 4-hydroxybutyraldehyde
