Extended Data Figure 6: Structure models of the pre- and post-DNA-ejection L loops.
From: The bacteriophage ϕ29 tail possesses a pore-forming loop for cell membrane penetration
a, Post-DNA-ejection L loop structure modelled with RosettaCM using the electron microscopy map as a restraint and fitted into the post-DNA-ejection tail electron microscopy map. The gp9 structure is shown in a ribbon representation. The L loops are coloured red. The rest of the structure is coloured grey. b, Structural comparison of the pre- and post-DNA-ejection L loop structures. Left, pre-DNA-ejection gp9 structure shown in a ribbon representation with the L loops coloured red. Right, post-DNA-ejection gp9 structure shown in a ribbon representation with the modelled structure of the flexible region coloured cyan and the rest of the L loop coloured red.
