Characterization-Introduction of Tag-Catcher system to co-display PETase and MHETase
To attain co-display, we combined our display system with two selective protein binding systems, SpyTag-SpyCatcher and SnoopTag-SnoopCatcher. In our experiment, GFP and RFP were used to indicate the successful construction of Spycatcher/Spytag and Snoopcatcher/Snooptag systems. We initially tried two catcher types with a ratio of 1:3.

GFP+ and RFP+ suggested the successful construction of Spycatcher/Spytag system and Snoopcatcher/Snooptag system.
