(A) Model of decoration protein trimer highlighting positions of the
β tulip domains (blue) within the assembly.
(B) P74–26 gp87 trimer highlights difference in trimer assembly
characterized by a ~20° outward rotation of each of the gp87
trimer subunits (see also Video S2). The N-terminal capsid binding region of both crystal
structures is disordered, and is drawn as proportional dotted lines in (B) and
(C).
(C) Structure of the λ gpD trimer shows the orientation of gpD
from the top of the capsid (left) and rotated 90° to the side
(right).
