The Small Metal-Binding Protein SmbP Improves the Expression and Purification of the Recombinant Antitumor-Analgesic Peptide from the Chinese Scorpion Buthus martensii Karsch in Escherichia coli
Abstract:We have recently shown that SmbP, the small metal-binding protein of Nitrosomonas europaea, can be employed as a fusion protein to express and purify recombinant proteins and peptides in Escherichia coli. SmbP increases solubility, allows simple, one-step purification through affinity chromatography, and provides superior final yields due to its low molecular weight. In this work, we report for the first time the use of SmbP to produce a recombinant peptide with anticancer activity: the antitumor-analgesic pep… Show more
