Beschreibung
Zusammenfassung:	The invention is directed to methods and compositions for the expression and purification of products such as peptides and proteins in microorganisms. In particular, pre-products are expressed recombinantly, wherein the cytoplasm of the microorganism alters the expressed pre-products to produce products in an active/final or otherwise desirable form. Alterations associated with expression of a desired recombinant product include shifting of the redox state of the cytoplasm to allow proper protein folding, site-directed cleavage of pre-proteins to activate the protein, site-directed cleavage of an unwanted methionine from the N terminus of the protein, and/or one or more ligations to form desired protein configurations, all within the same cell.
