Abstract: The present invention relates generally to robust split inteins. The split inteins described herein are active over a large temperature range, including temperatures as low as 0° C., over a wide pH range, and in the presence of chaotropic salts. The split inteins also show high tolerance to sequence variability in fused heterologous polypeptides and therefore are useful in protein purification and engineering techniques.

Abstract: A fusion protein that is expressed in a recombinant protein body-like assembly (RPBLA) in host eukaryotic cells and organisms is disclosed. More particularly, a biologically active polypeptide fused to a protein sequence that mediates the induction of RPBLA formation is expressed and accumulated in host cells after transformation with an appropriate vector. The eukaryotic host cell does not produce protein bodies in the absence of the fusion protein. Methods for preparing and using the RPBLAs and the fusion protein are also disclosed, as are nucleic acid molecules that encode the fusion proteins.
