Chaperonin assisted polypeptide folding and assembly: implications for the production of functional proteins in bacteria.

Production of biologically active foreign proteins with correct three-dimensional structures is often difficult in bacteria. Recent advances demonstrate that, for some proteins at least, their correct folding and assembly is facilitated by a class of proteins known as molecular chaperones. An understanding of the function of molecular chaperones may assist in the synthesis in bacteria of functional foreign proteins produced by recombinant techniques.
