Here we report the isolation and characterization of a previously undescribed mink respiratory coronavirus (MRCoV) from farmed minks with pneumonia. Notably, MRCoV uses angiotensin-converting enzyme 2 (ACE2) as an entry receptor and can infect mink, bat, monkey and human cells. Cryo-electron microscopy analyses revealed that the MRCoV receptor-binding domain (RBD) binds to the same interface on ACE2 receptors as the RBD of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) despite structural differences. We identify the key determinants on the RBD of MRCoV and ACE2 that confer efficient binding. HKU5-33S, a bat coronavirus closely related to MRCoV, uses ACE2 of the bat Pipistrellus abramus for cell entry and requires only two amino acid substitutions to adapt to mink ACE2. SARS-CoV-2 protease and polymerase inhibitors potently block MRCoV infection, thereby indicating a potential therapeutic strategy. Collectively, these findings enhance our understanding of coronavirus receptor dynamics and highlight their zoonotic potential. Given the risks posed by fur farms as reservoirs for emerging pathogens, our study underscores the need for enhanced surveillance to mitigate future coronavirus outbreaks.
