The present invention provides isolated human and bovine TNF-&#x3b1; convertases, nucleic acids and; recombinant vectors encoding the same, host cells comprising the nucleic acids and vectors, and methods for making the convertases using the host cells. This invention further provides antibodies and antigen binding fragments thereof which specifically bind to the convertases and are useful for treating medical conditions caused or mediated by TNF-&#x3b1;. Also provided are screening methods for identifying specific inhibitors of mammalian TNF-&#x3b1; convertases, and for identifying nucleic acids encoding such convertases.

The present invention provides isolated human and bovine TNF-.alpha. convertases, nucleic acids and recombinant vectors encoding the same, host cells comprising the nucleic acids and vectors, and methods for making the convertases using the host cells. This invention further provides antibodies and antigen binding fragments thereof which specifically bind to the convertases and are useful for treating medical conditions caused or mediated by TNF-.alpha.. Also provided are screening methods for identifying specific inhibitors of mammalian TNF-.alpha. convertases, and for identifying nucleic acids encoding such convertases.

Mammalian TNF-.alpha. convertases

Biologically active human inducible nitric oxide synthase (iNOS) is expressed in E. coli. The expression of soluble, active iNOS is dependent on its coexpression with calmodulin.

Expression of human inducible nitric oxide synthase

Strains of E. coli are provided which are capable of secreting heterologous recombinant proteins through the outer cell wall and directly into the culture medium. Methods are also provided for making and identifying such strains, and for using them to make heterologous proteins that have high biological activity, without the need for cell disruption.
