Published in Gene Therapy Weekly, April 2nd, 2009

According to recent research published in the journal Biotechnology Letters, "An E. coli vector system was constructed which allows the expression of fusion genes via a l-rhamnose-inducible promotor. The corresponding fusion proteins consist of the maltose-binding protein and a His-tag sequence for affinity purification, the Saccharomyces cerevisiae Smt3 protein for protein processing by proteolytic cleavage and the protein of interest."

"The Smt3 gene was codon-optimized for expression in E. coli. In a second rhamnose-inducible vector, the S. cerevisiae Ulp1 protease gene for processing Smt3 fusion proteins was fused in the same way to maltose-binding protein...
