Abstract
The invention discloses modified signal peptides derived from wild-type signal peptides of the type that are capable of forming membrane-bound lipoproteins and methods for making such modified signal peptides and DNA sequences encoding them. Modified signal peptides of the invention and DNA sequences encoding them are useful for increasing the secretion of heterologous gene products produced by transformed host organisms. The invention further discloses a method for producing recombinant DNA sequences in vivo.
