Abstract
The invention is a plasmid vector in which a first DNA sequence expressionable for a selected gene product is ligated to a positive retroregulatory element in a relationship thereto whereby expression of the selected gene product is enhanced. The first DNA sequence is furthermore operably linked to a second and third DNA sequence operably linked to one another which are respectively the P.sub.L promoter and a DNA sequence corresponding to an N gene ribosome binding site. Microorganisms transformed with the plasmid are also claimed.
