Asparaginyl ligases have been utilized as valuable tools for protein engineering, such as through site-specific bioconjugation or surface modification, however, their application is limited due to time-consuming preparation processes and unstable activities. Here, the authors develop a truncated protein ligase OaAEP1-C247A-aa55-351 from an OaAEP1-C247A mutant, which simplifies the preparation steps, tolerates a wider pH range, and enhances the catalytic activities by using efficient recognition and nucleophile motifs.
