Characterization and overall structure of the hexameric terminase assembly. (A) Model for herpesvirus procapsid during DNA packaging. (B) Characterization of the terminase complex analyzed by analytical ultracentrifugation, SDS-PAGE and electron microscopy. (C) Representative curves of the MESG-based assays to measure the ATPase activities of wild-type and R346A mutant hexameric terminase rings and wild-type monomer terminase complex. (D) CryoEM map of the hexameric terminase assembly. The inset shows the blocked-based reconstruction for one terminase complex, which consists of pUL15 (blue), pUL28 (green) and pUL33 (magenta). (E and F) Atomic models for the hexameric terminase assembly and the terminase complex. Color scheme is the same as Fig. 1D
