The molecular basis for SARS-CoV-2 recognized by dog ACE2
Abstract SARS-CoV-2 can infect many domestic animals, including dogs. Herein, we show that dog angiotensin converting enzyme 2 (dACE2) can bind to SARS-CoV-2 spike (S) protein receptor binding region (RBD), and that both pseudotyped and authentic SARS-CoV-2 can infect dACE2-expressing cells. we solved the crystal structure of RBD in complex with dACE2 and found that the total numbers of contact residues, contact atoms, hydrogen bonds and salt bridges at the binding interface in this complex are slightly fewer than those in the complex of the RBD and human ACE2 (hACE2). This result is consistent with the fact that the binding affinity of RBD to dACE2 is lower than that to hACE2. We further show that a few important mutations in the RBD binding interface play a pivotal role in the binding affinity of RBD to both dACE2 and hACE2, and need intense monitoring and controlling..
