Figure 4.
Fig. 4. Primary sequence and distribution of surface charge
and hydrophobicity in LB5 and LB6 (lowest energy structure).
Residues shown in bold are common to both modules; residues
marked with filled squares are coordinated to calcium in LB5;
and those underlined are unique (across all modules) to LB5
between the first and last cysteine residue. Modules in a and d
have an similar orientation to that of Fig. 2, then are shown
(left to right) rotated in two anticlockwise 90° steps, as
viewed from the bottom, around the vertical axis. Positively
charged functional groups are shown in blue, negatively charged
groups are shown in red, and the sidechains of large non-polar
residues (F, I, L, M, V, W) are shown in green.
