More Information
Summary:A recombinant expression system for the expression of a poly amino acid, peptide or protein is provided. The poly amino acid of interest is expressed as a fusion protein that includes an amino acid sequence recognized and cleaved by a Ulp1 protease. The amino acid sequence joined to the poly amino acid of interest is preferably from a SUMO (small ubiquitin-like molecule) protein. This sequence imparts favorable solubility and refolding properties to the fusion protein. A purification tag may also be incorporated into the fusion protein for ease of isolation. This recombinant expression system is particularly advantageous for expression and rapid and highly specific cleavage and purification of poly amino acids that have low solubilities or are difficult to express in other systems.
