Mutant 3-hydroxybutyric acid dehydrogenase derived from Alcaligenes faecalis and related methods and uses.

摘要

The present invention relates to a mutant 3-hydroxybutyrate dehydrogenase (3-HBDH) with improved performance relative to the wild-type 3-HBDH, a nucleic acid encoding the mutant 3-HBDH, a cell comprising the mutant 3-HBDH or the nucleic acid, a method of determining the amount or concentration of 3-hydroxybutyrate in a sample, the use of the mutant 3-HBDH for determining the amount or concentration of 3-hydroxybutyrate in a sample, and a device for determining the amount or concentration of 3-hydroxybutyrate in a sample.
