It binds to the human aminopeptidase N (hAPN) through the receptor binding domain (RBD) of its spike (S) protein to achieve host recognition. We present the cryo-electron microscopy structure of two HCoV-229E S protein in complex with a dimeric hAPN to provide structural insights on how the HCoV-229E S protein opens up its RBD to engage with its host receptor, information that is currently missing among alphacoronaviruses to which HCoV-229E belong. We quantitatively profile the glycosylation of HCoV-229E S protein and hAPN to deduce the glyco-shielding effects pertinent to antigenicity and host recognition. Finally, we present an atomic model of fully glycosylated HCoV-229E S in complex with hAPN anchored on their respective membrane bilayers to recapitulate the structural basis of the first step of host infection by HCoV-229E. | ||||||||||||||||||||||||||||||
