Abstract
Dihydroxy-acid dehydratase (DHAD) variants that display increased DHAD activity are disclosed. Such enzymes can result in increased production of compounds from DHAD requiring biosynthetic pathways. Also disclosed are isolated nucleic acids encoding the DHAD variants, recombinant host cells comprising the isolated nucleic acid molecules, and methods of producing butanol.
