Fig. 1. Overview of the S2N51 structure and its critical
location in the myosin II dimer. (a) Schematic diagram of myosin
II in an on-state conformation. (b) Schematic diagram of an
expanded view of the construct crystallized in the present
study. (c) Ribbon diagram of the best-ordered structure of
S2N51, crystallized in the monoclinic C2 space group. Gray
indicates C-terminally attached GCN4 leucine zipper and
N-terminally attached tetrapeptide tag. S2N51 is colored by
temperature factor (see Fig. 2). The box indicates the region
immediately adjacent to the head–rod junction and is described
in more detail in Fig. 2 and Fig. 3. (d) Schematic diagram of
the off-state conformation of regulated myosin II (adapted from
Ref. 3).
