Abstract

An acid-cleavable peptide linker comprising aspartic acid and proline residues is disclosed. The acid-cleavable peptide linker provides an altered sensitivity to acid-hydrolytic release of peptides of interest from fusion peptides of the formula PEP1-L-PEP2. The inventive linker, L, is described in various embodiments, each of which provides substantially more rapid acid-release of peptides of interest than does a single aspartic acid-proline pair. In an additional aspect, a method of increasing the stability of an acid cleavable linkage to acid hydrolysis is also provided.
