Two proposed dimer interfaces. Crosslinking studies indicate several points of attachment at the top (outer) end of S1 (red) [4]. The binding of Zn2+ to various hHV1 mutants with His140 or His193 (aqua) replaced by Ala suggested that high-affinity bidentate Zn2+ binding occurs at the dimer interface [21].
