Figure 4. The structure of IIA^mtl. (a) Stereo Ca trace of
IIA^mtl, molecule A[I], with N and C termini and every tenth
residue labelled. (b) Ribbon stereo view of the structure of
IIA^mtl, molecule A[I], generated using the program MOLSCRIPT
[49]. Strands are shown in red, helices in yellow and loops in
light yellow. The catalytic His65 is shown in a ball and stick
representation. Also shown are the conserved Arg49 and His111.
The N and C termini are indicated. See also Kinemage
