摘要： 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.

摘要： It is intended to provide techniques whereby a target protein is efficiently obtained as a normal protein even in the case of a protein which can be hardly expressed by usual recombinant DNA techniques. A fusion protein composed of a molecular chaperone, an intervening protein having an activity of cleaving a peptide bond, and a target protein is prepared, from which fusion protein the target protein is cleaved by the action of the intervening protein having the activity of cleaving a peptide bond. Examples of the intervening protein having the activity of cleaving a peptide bond include an intein and a protein consisting of a partial sequence of the intein.
