Figure 4. The N-terminal helix a0. (a) Stereo view of the
final 2F[o] -F[c] electron density map contoured at the 1.5s
level. The refined model (ball-and-stick) is superimposed,
displaying the residues 256 to 265. (b) Stereodiagram showing
the main interactions of helix a0 with the PTP domain. Only
specifically conserved residues of the KIM-containing PTPs
family are represented. Residues of helix a0 are in green, those
of helix a5 are in blue and those of the loop between Ile292 and
Asp298 are in magenta.
