By analysis of knockout mutants of bdh1 or bdh2 using anionexchange column chromatography, it was shown that a novel BDH besides BDH1 and BDH2 was present in R. pickettii T1. The third BDH (BDH3) was partially purified by column chromatography, and the enzyme had the N-terminal amino acid sequence different from those of BDH1 and BDH2. In Southern blotting with bdh2 as a probe, bdh3 was detected and cloned, and the purified gene product of bdh3 expressed in Escherichia coli showed higher specific activity than those of BDH1 and BDH2., ■Full-Length Paper■ By a grand of Research Institute for Integral Science, Kanagawa University}, pages = {13--17}, title = {Characterization of Third 3-Hydroxybutyrate Dehydrogenase in Ralstonia pickettii T1}, volume = {19}, year = {2008} }
