In [[enzymology]], a '''5-(3,4-diacetoxybut-1-ynyl)-2,2'-bithiophene deacetylase''' ({{EC number|3.1.1.66}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:5-(3,4-diacetoxybut-1-ynyl)-2,2'-bithiophene + H<sub>2</sub>O <math>\rightleftharpoons</math> 5-(3-hydroxy-4-acetoxybut-1-ynyl)-2,2'-bithiophene + acetate

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[5-(3,4-diacetoxybut-1-ynyl)-2,2'-bithiophene]] and [[water|H<sub>2</sub>O]], whereas its two [[product (chemistry)|products]] are [[5-(3-hydroxy-4-acetoxybut-1-ynyl)-2,2'-bithiophene]] and [[acetate]].

This enzyme belongs to the family of [[hydrolase]]s, specifically those acting on carboxylic [[ester]] bonds.  The systematic name of this enzyme class is '''5-(3,4-diacetoxybut-1-ynyl)-2,2'-bithiophene acetylhydrolase'''. Other names in common use include '''diacetoxybutynylbithiophene acetate esterase''', and '''3,4-diacetoxybutinylbithiophene:4-acetate esterase'''.
