Abstract
A DNA expression vector is described which is derived from the highly efficient trp operon. The expression vector provides for the direct expression of an inserted gene or cDNA. Using the expression vector described herein, it is possible to obtain the protein coded by the gene or cDNA directly and not as a fusion protein. The expression vector comprises the promoter, operator and leader ribosomal binding site of the trp operon.
