Figure 19.
Interaction of CRAMP (16–33) with FtsZ. The N-terminus of FtsZ is blue. The H7 helix is green. The C-terminus is red, and CRAMP (16–33) is magenta. A) Proposed CRAMP (16–33) binding site located near the T7 loop. B) Magnification of CRAMP (16–33) binding site. C) Residue interactions forming salt bridges (green) and hydrogen bonds (orange).
