Methods of inhibiting S. aureus propagation, and screening for compounds that inhibit S. aureus propagation, are described. A method of inhibiting S. aureus propagation comprises either inhibiting or stabilizing ribosomal binding of a specific S. aureus tRNA in the S. aureus by an amount sufficient to inhibit S. aureus protein expression. A method of screening for compounds useful for inhibiting S. aureus propagation comprises contacting a specific S. aureus tRNA to a ribosome that binds that tRNA in the presence of the test compound and an mRNA that codes for methionine and arginine (i.e., includes the sequence AUGAGA), and then determining whether the compound inhibits the binding of that tRNA.
