Abstract: The cDNA of α and β subunit of human pyruvate dehydro genase(hPDH) was cloned to pQE9, in tandom, for construction of expression vector pHsaE1αβ. The recombined hPDH was expressed in E.coli. The protei n was purified by affinity chromatography. Its biochemical properties were chara cterized.

Key words: human pyruvate dehydrogenase, cloning, expression vector
