Yeast surface display (YSD) system has been widely used in protein engineering since it was established 20 years ago. Combined with fluorescence-activated cell sorting (FACS) technology and directed evolution, YSD has been proven of its extraordinary effectiveness for molecular engineering of various target proteins, especially for antibodies. Recently, a few remarkable efforts were exploited to modify the original Aga1-Aga2 YSD for the non-antibody protein engineering with successful outcomes, expanding its application on oxidase, Class II major histocompatibility complex (MHC II), protease, sortase, lipoic acid ligase etc. Here, the methodologies of these optimized Aga1-Aga2 YSD technologies were introduced, and the recent progress of non-antibody protein engineering using these methods was summarized.
