Substitutions of conserved amino acids in the receptor-binding domain of the spike glycoprotein affect utilization of murine CEACAM1a by the murine coronavirus MHV-A59 2005-03-30 .txt text/plain 7779 345 56 Cell lines from host species that are normally resistant to MHV, porcine coronavirus [transmissible gastroenteritis virus (TGEV)] or human coronavirus strain 229E (HCoV-229E) are rendered susceptible to infection by transfection with cDNA encoding the specific coronavirus receptors mCEACAM1a, porcine aminopeptidase N (pAPN) (Delmas et al., 1992; Dveksler et al., 1991; Yeager et al., 1992) . Since some of the aa substitutions in the RBD of S were chosen to reflect residues found in S330 of related rat, bovine or human coronaviruses in group II (Fig. 1A) , we examined the ability of the SA59 B, S33R A, S33G C, T62S A, T62A A, L65H C, L65A C, L79M/T82M A, L79A/ T82A B, Y162F A, K183R A and K183G A viruses to infect non-murine cells lines that are normally resistant to MHV-A59 infection. ./cache/cord-289045-vft163v0.txt ./txt/cord-289045-vft163v0.txt
