Figure 1. (a) Cartoon representations of the OmCI molecule
from the P2[1]2[1]2[1]-A crystal form. Colour: blue to red, from
N terminus to C terminus. The cysteine side-chains and the
ricinoleic acid ligand are shown in stick representation, with C
atoms coloured orange, O red and S green. The strands and
helices are labelled following the tick lipocalin
nomenclature.^36 (b) OmCI molecular surface coloured by
electrostatic potential, in the same orientations as in (a).
Contours: − 2 kT/e, red; + 2 kT/e, blue. The pictures were
produced with the PyMol [http://www.pymol.sourceforge.net/]. The
electrostatic potential was computed with the program APBS^42,
run within PyMol, with the following parameters: ε[protein] =
2.0; ε[solvent] = 78.0; ionic strength, 150 mM NaCl. In (a) and
(b), views 1 and 2 are rotated by 90° around the horizontal
axis.
