STABILIZATION OF CYCLIC PEPTIDE STRUCTURES

摘要

In various aspects, the invention provides methods for cyclizing proteins, including methods for enhancing the stability of cyclized proteins under cytosolic conditions. The invention also provides various methods for using the cyclized proteins. For example, cyclized proteins of the invention may be used in screening assays analogous to the yeast two hybrid assay. Selected embodiments of the invention provide cyclized single chain variable fragment (ScFv) molecules, including molecules in the form of an immunoglobulin fold.
