A novel thermostable chimeric beta-galactosidase was constructed by fusing a poly-His tag to the N-terminal region of the beta-galactosidase from Thermus sp. strain T2 to facilitate its overexpression in Escherichia coli and its purification by immobilized metal-ion affinity chromatography (IMAC). The poly-His tag fusion did not affect the activation,(More)
