COMPOSITIONS AND METHODS FOR PEPTIDE EXPRESSION AND PURIFICATION USING A TYPE lll SECRETION SYSTEM

摘要

Disclosed are compositions and methods for expressing and purifying a peptide of interest using a Flagellar Type III secretion system. Disclosed are nucleic acid sequences that contain a FigM nucleic acid sequence, a cleavage site, and a nucleic acid sequence of interest. Also disclosed are polypeptides that contain FigM, a cleavage site and a peptide of interest. Methods of producing polypeptides that have FigM, a cleavage site and a peptide of interest are provided.
