Method for over-expression of rapid purification of biosynthetic proteins (U.S. Patent Number 6,077,694)

The subject invention relates to a method of producing and purifying large quantities of a biosynthetic protein. The gene which codes for the protease is placed between the binding domain of a gene which codes for a binding protein and a gene coding for the target protein of interest. The fused gene construct is inserted in an expression vector which is then introduced into a host cell.
