Abstract
The subject invention concerns a novel and superior recombinant DNA expression/secretion system for use in prokaryotic organisms to produce useful proteins. The system can be used to have proteins secreted by an engineered prokaryotic host where normally the proteins are not secreted by the host. Also, when using the expression system, proteins are expressed at much higher levels than when the expression system is not used.
