Pace expression into host cells and methods of use thereof.

They ARE PROVIDED PRODUCTION compositions and methods for endopeptidase and improve processing efficiency heterologous polypeptide precursor polypeptide A MATURE, including proteins REQUIRING GAMMA FOR BIOLOGICAL ACTIVITY carboxylation. These compositions and methods use an endopeptidase mammalian PACE (PHASE ELECTRONICALLY CONTROLLED MATRIX) RECOMBINED that is specific to be placed in a AMINO dibasic acid.
