Figure 2.
Figure 2. Cross sections of the two dimers near residue 38.
(a) Section of the Len dimer perpendicular to the twofold axis
between the domains. Gln38 of each monomer forms hydrogen bonds
with the other monomer's Gln38 across the twofold axis. (b)
Section of the LenQ38E dimer perpendicular to the twofold axis
between the domains, illustrating the complementarity of the
domains. Internal water molecules connect each Tyr36 to
carbonyls of residues 44. The closest distance between charged
residues Lys30 and Glu38 is 11 å. (This figure was generated
using the program SETOR [28].)
