pPSY: a vector for the stable cloning and expression of streptomycete single gene phenotypes in Escherichia coli.

Abstract excerpt

pPSY is a 12kb cloning vector derived from the IncW plasmid R388, which provides a rapid and easy way to stably clone phenotypes encoded in DNA segments <10kb. In the present study three different genes were amplified by PCR, cloned into pGEM-T Easy and sub-cloned into the EcoRI site of pPSY. The first gene, vioA, is a FAD-dependent l-tryptophan amino acid oxygenase from the high G+C Gram-negative bacterium...
