HPLC traces and MS analysis of bacteriophage M6 and ViI nucleosides. The trace in Top was obtained from bacteriophage λ to show the retention of canonical nucleosides. M6 and ViI show a fifth major peak corresponding to the hypermodified base. The protonated molecular ion detected for each hypermodified base is indicated as well as a hypothetical combination of atoms to account for the observed masses. dA, 2′-deoxyadenosine; dG, 2′-deoxyguanosine; dC, 2′-deoxycytidine; dT, thymidine.
