title: Simultaneous single-step purification of thiolase and NADP-dependent 3-hydroxybutyryl-CoA dehydrogenase from Clostridium kluyveri.
abstract: Thiolase and NADP-dependent 3-hydroxybutyryl-CoA dehydrogenase from Clostridium kluyveri were purified by ion-exchange chromatography to near homogeneity in a simultaneous, single-step procedure. The yield of both enzymes was greater than 80%. Thiolase was purified approximately 8-fold with sp act 115 units/mg, whereas 3-hydroxybutyryl-CoA dehydrogenase was purified 14-fold with sp act 292 units/mg. Isoelectric points of the enzymes are 7.7 for thiolase and 7.8 for 3-hydroxybutyryl-CoA dehydrogenase. Milligram quantities of each of these enzymes are readily obtained from this fatty acid-producing organism.
