Figure 4. Surface characteristics. (a) and (b) Sequence
similarity between PRL-1 and PRL-3 is mapped onto the PRL-1
surface. The 100% identical, similar and different residue
properties, as defined by the program ALSCRIPT37 are colored
white, green and cyan, respectively. The active-site surface and
the opposite surface are presented in (a) and (b), respectively.
(c) and (d) Electrostatic potential surfaces of PRL-1 (c) and
VHR (d) are presented. Positive and negative potentials are
colored blue and red, respectively. The point of view is the
same as (a). Residues near the active-site are labeled.
