Acetoxybutynylbithiophene deacetylase

In enzymology, an acetoxybutynylbithiophene deacetylase (EC 3.1.1.54) is an enzyme that catalyzes the chemical reaction

5-(4-acetoxybut-1-ynyl)-2,2'-bithiophene + H₂O ⇌ 5-(4-hydroxybut-1-ynyl)-2,2'-bithiophene + acetate

Thus, the two substrates of this enzyme are 5-(4-acetoxybut-1-ynyl)-2,2'-bithiophene and H₂O, whereas its two products are 5-(4-hydroxybut-1-ynyl)-2,2'-bithiophene and acetate.

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is 5-(4-acetoxybut-1-ynyl)-2,2'-bithiophene O-acetylhydrolase. Other names in common use include acetoxybutynylbithiophene esterase, and 5-(4-acetoxy-1-butynyl)-2,2'-bithiophene:acetate esterase.
