Fig. 4: Tilt between the portal and the capsid and potential metal-binding clusters.
From: Structural morphing in a symmetry-mismatched viral vertex
The portal assembly and the surrounding gp23* capsomers are colored and labeled as in Fig. 1a. a Tilt between the portal and the capsid. The tilt axis, portal axis, and capsid axis are shown. b Hydrophobic interaction between gp20 α2 and gp23* capsomers. c The potential methionine-metal clusters formed between the N-whisker methionine (M1) of subunits 1 and 6 of gp20 and subunits S5 and S2 of gp23*. Residues involved in forming the metal binding sites are labeled.
