Rhesus TRIMCyp (RhTC) is a potent antiviral that inhibits the replication of diverse HIV viruses. Here we show that it has acquired the ability to target multiple viruses by evolving an active site that interconverts between multiple conformations. Mutations that have relieved active site constrains allow RhTC to dynamically sample conformational space, including radically different conformers that are used to target both HIV-1 and HIV-2 viruses. Introduction of a reversible constraint into RhTC allows specificity to be switched between a single conformation specific for HIV-1 and a dynamic ensemble that targets multiple viruses. These results illustrate how conformational diversity can be used to expand the target diversity of innate immune receptors and help explain the efficiency of antiviral recognition.
