New Phytologist, Volume 238, Issue 4, Page 1534-1545, May 2023., 2023 Summary Peptide asparaginyl ligases (PALs) are useful tools for precision modifications of proteins and live‐cell surfaces by ligating peptides after Asn/Asp (Asx). They share high sequence and structural similarity to plant legumains that are generally known as asparaginyl endopeptidases (AEPs), thus making it challenging to identify PALs from AEPs ...
