Figure 2.

Crystal structure of Amuc_1100*. (a) Overall structure of Amuc_1100*. The proteins pack as dimers in the crystal lattice. The two protomers are colored pale cyan and marine blue. (b) Alignment of the two protomers of Amuc_1100* (r.m.s.d. = 0.4 Å). (c) General topology of Amuc_1100*; rectangles represent α-helices and arrows represent β-sheets. The dashed lines represent absent fragments. The lower panel shows the struucture of the Amuc_1100* monomer in the corresponding colors. All structure-related figures were prepared in PyMOL (Schrödinger).
