N-terminal extensions ("tags" have proven valuable for producing peptides using high throughput recombinant expression technologies. However, the applicability is hampered by the limited options for specific and efficient proteases to release the fully native sequence without additional amino acids in the N-terminal. Here we describe the Escherichia coli (E. coli) expression, purification and characterization of engineered variants of Xaa-Pro dipeptidyl aminopeptidase (Xaa-Pro-DAP) derived from Lactococcus lactis for cleavage of Gly-
