WebJul 1, 2003 · Abstract. Three foldases—the apical domain of GroEL (mini‐chaperone) and two oxidoreductases (DsbA and DsbC) from Escherichia coli—were studied in refolding a protein with immunoglobulin fold (immunoglobulin‐folded protein) that had been produced as inclusion bodies in E.coli.The foldases promoted the refolding of single‐chain antibody … WebWhile the formation of inclusion bodies is beneficial in protein isolation from other cellular components, most of the recombinant proteins from inclusion bodies are misfolded and have lost their biological activity. Protein refolding allows the misfolded protein to rearrange into its native conformation which exhibits its biological activity ... WebThe predominant host is Escherichia coli.
