Multiple sequence alignment of SARS‐CoV‐2 receptor‐binding domain (RBD) of spike glycoprotein (S). The contact amino acid residues of RBD that interacts with ACE2 receptor are marked with red boxes. All six amino acid residues exactly matches with Malayan pangolin CoV strains MP789 (NCBI acc no: MT084071) [62] and GD/P2S (GISAID acc no: EPI_ISL_410544) [63]; both the samples originated from the Guangdong Wildlife Rescue Center. These Malayan pangolins were rescued by the Anti‐Smuggling Customs Bureau in March 2019. This suggests that ancestral strain of SARS‐CoV‐2 might have infected Malayan pangolins
