New vectors for the in vitro generation of alkaline phosphatase fusions to proteins encoded by G+C-rich DNA
Abstract
Phagemid vectors were constructed to allow fusions of alkaline phosphatase to proteins encoded by G+C-rich DNA, by engineering a BstBI site (TT/CGAA) in front of a phoA gene that lacks an encoded signal peptide. Three vectors (pJDT1, pJDT2 and pJDT3), each with phoA in a different reading frame with respect to the BstBI site, were produced; a lacP region is present in each plasmid upstream of the BstBI site. The presence of the BstBI site allows the random cloning of G+C-rich DNA digested with a number of restriction enzymes that generate cohesive ends.
