Materials and Methods. Cloning, expression, and purification. The Tas gene was polymerase chain reaction (PCR) amplified from E. coli MG1655 genomic DNA and subcloned into a pDONR201 plasmid using the Gateway technology (Invitrogen). For expression, the coding sequence was transferred into a pDEST14 plasmid using site-specific recombination (Invitrogen). The protein was produced in E. coli strain BL21 Star (DE3)(Invitrogen) that was transformed with pDEST14. Cells were grown on LB media containing 100 g/L ampicillin at 37 C to an A600 of 0.6 and induced with 1 mM isopropyl-D-thiogalactoside for 3 h. The protein was purified by column chromatography in two steps using Source 30Q (Pharmacia) and Butyl-560M (Toyopearl).Abbreviations: NADPH, nicotinamide adenine dinucleotide phosphate; TIM, triosephosphate isomerase; KVB2, voltage-dependent K channel subunit; RMSD, root mean square deviation; PCR, polymerase chain reaction; IMCA-CAT, Industrial Macromolecular Crystallography Collaborative Access Team; APS, Advanced Photon Source; CCD, charge-coupled device.
