Surface and interior structure of <i>B. pseudomallei</i> BpaA third head domain.

<p>A. One monomer of the BpaA head is sown in green ribbons with side chains shown in stick representation, while the other two monomers of the trimer are shown as a translucent molecular surface rendering in gray. B. Electrostatic surface potential mapped onto a molecular surface rendering of the third BpaA head domain. Blue indicates regions of positive charge and red indicates regions of negative charge.
