Figure 1

Structure of herpesvirus nuclear egress complex (NEC). Structures of the heterodimeric NEC of the alphaherpesviruses pseudorabies virus (PrV) [11,12] and herpes simplex virus 1 (HSV-1) [11] as well as of the betaherpesvirus human cytomegalovirus (HCMV) [13,14]. The N-terminal extended α-helix of pUL31 (bottom) inserted into the groove in pUL34 (top) is apparent. In the HSV-1 NEC structure, the second pUL34 α-helix lining the groove has not been resolved. Red circles denote putative capsid-interaction domains.
