Enzymatic clickable functionalization of peptides via computationally engineered peptide amidase

The computationally engineered peptide amidase exhibits great promising potential in the C-terminal modification of peptides using prop-2-yn-1-amine (PYA) or prop-2-en-1-amine (PEA) as the nucleophile. Subsequently, modified peptides could be further functionalized via click reaction without elaborate isolation of the intermediate.
