(a) B-factor representation of the PX and PH domains of Bem3 [putty representation from PyMOL; colours indicate low B factors (blue) to high B factors (red)]. The average B factor for the whole structure is 81 Å2 (PX domain, 71 Å2; PH domain, 96 Å2). Additionally, amino acids within the interface between the domains are shown. (b) Surfaces of neighbouring molecules in the crystal show that the PX domain has large contact areas (cyan surfaces), whereas the PH domain does not (red surfaces). |
