A structural explanation for these findings was provided from our previous cryo-EM structures of CT(Pro32) and rAmy(Tyr37)-bound AMYRs structures where the bulky phenolic side chain of Y37 rAmy forms perpendicular stacking interactions with W79 ECD 15 , and additional interactions with the respective RAMP protomer that are likely important for selectivity of rAmy for AMYRs over CTR
