ABSTRACT:
This invention provides a recombinant protein expression system using a host and cell-free translation system, and is capable of universally expressing a large amount of any protein as soluble protein, while preventing toxicity in hosts, formation of inclusion bodies, and decomposition with proteases. Such may be achieved by expressing the desired protein as a fusion protein with chaperonins, such as about 60 kDa molecular chaperones, 60 kDa heat shock proteins, or thermosomes, and accommodating the desired protein inside of a stereostructure of a chaperonin. The present invention provides a process for producing a protein, which comprises transcribing and translating a gene containing a gene encoding the linked chaperonin subunits and a gene encoding a desired protein thereby synthesizing a fusion protein having the desired protein linked via a peptide linkage to the linked chaperonin subunits.
