Molecular Basis of Binding between Middle East Respiratory Syndrome Coronavirus and CD26 from Seven Bat Species.

ABSTRACT: Continued reports of Middle East respiratory syndrome coronavirus (MERS-CoV) infecting humans have occurred since the identification of this virus in 2012. MERS-CoV is prone to cause endemic disease in the Middle East, with several dozen spillover infections to other continents. It is hypothesized that MERS-CoV originated from bat coronaviruses and that dromedary camels are its natural reservoir. Although gene segments identical to MERS-CoV were sequenced from certain species of bats and one species experimentally shed the virus, it is still unknown whether other bats can transmit the virus. Here, at the molecular level, we found that all purified bat CD26s (bCD26s) from a diverse range of species interact with the receptor binding domain (RBD) of MERS-CoV, with equilibrium dissociation co
