We noticed the missing structure deposition information in our manuscript published online on February 11, 2020, which are the PDB codes and EMDB map entries of the structure PACAP38-PAC1R-Gs (PDB code: 6M1I and EMDB entry: EMD-30048) and maxadilan-PAC1R-Gs (PDB code: 6M1H and EMDB entry: EMD-30047). We apologize for any inconvenience this missing information has caused. This correction does not affect the description of the results or the conclusion of this work.
