Escherichia coli plasmid vectors for high-level regulated expression of the bacteriophage lambda xis gene product.

The bacteriophage lambda Xis protein is one of the proteins required for site-specific excisive recombination by which the lambda prophage is excised from the Escherichia coli bacterial chromosome. We cloned the lambda xis gene under the control of several prokaryotic promoters to obtain a sufficient source of the protein for biochemical studies. Our results demonstrate that E. coli lac promoter and lambda pL promoter fusions to the xis gene produce high levels of Xis protein. Induction of the expression vectors results in a 10- to 50-fold increase in Xis activity. In addition, one of these plasmids allows the control of xis expression in vivo.[1]
