英文摘要nad+-dependent malic enzyme (nad-me) gene from escherichia coli k12 was inserted into an expression vector pet24b(+) and transformed into e coli bl21 (de3). recombinant nad-me was expressed upon iptg induction, purified with affinity chromatography, and biochemically characterized. the results showed that recombinant nad-me could be produced mainly in a soluble form. the monomeric molecular weight of recombinant nad-me was about 65 kda, whereas monomer, homotetramer, and homooctamer were formed in solution as revealed by nondenaturing polyacrylamide gel electrophoresis analysis. finally, the k-m, values of nad-me for l-malate and nad were determined as 0.420 +/- 0.174 and 0.097 +/- 0.038 mm, respectively, at ph 7.2. by using this over-expression and purification system, recombinant e coli k12 nad-me can now be obtained in large quantity necessary for further biochemical characterization and applications.
