Abstract

A group of bacterial dihydroxy-acid dehydratases having a [2Fe-2S] cluster was discovered. Bacterial [2Fe-2S] DHADs were expressed as heterologous proteins in bacteria and yeast cells, providing DHAD activity for conversion of 2,3-dihydroxyisovalerate to α-ketoisovalerate or 2,3-dihydroxymethylvalerate to α-ketomethylvalerate. Isobutanol and other compounds may be synthesized in pathways that include bacterial [2Fe-2S] DHAD activity.
