ⓘ Dihydroxy-acid dehydratase

In enzymology, a dihydroxy-acid dehydratase is an enzyme that catalyzes the chemical reaction

2.3-dihydroxy-3-methylbutanoate ⇌ {\displaystyle \rightleftharpoons } 3-methyl-2-oxobutanoate + H 2 O

Hence, this enzyme has one substrate, 2.3-dihydroxy-3-methylbutanoate, and two products, 3-methyl-2-oxobutanoate α-ketoisovaleric acid and H 2 O.

This enzyme participates in valine, leucine and isoleucine biosynthesis and pantothenate and coenzyme A CoA biosynthesis.

                                     

1. Nomenclature

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 2.3-dihydroxy-3-methylbutanoate hydro-lyase 3-methyl-2-oxobutanoate-forming. Other names in common use include

  • and 2.3-dihydroxy-acid hydro-lyase.
  • DHAD,
  • 2.3-dihydroxyisovalerate dehydratase,
  • alpha,beta-dihydroxyacid dehydratase,
