Physical properties of purified Vap proteins. (a) 15% SDS–PAGE analysis (molecular-weight markers 66.2, 31.0, 21.5 and 14.4 kDa) showing the effects of chymotrypsin digestion on VapD-full at a chymotrypsin:VapD weight ratio of 1:100. Lanes 1 and 2 are from the same gel, although intervening lanes have been cropped. (b) Circular-dichroism spectra of VapD-full and VapD-core. (c) SEC-MALLS analyses of VapD-full and VapD-core. The refractive index (RI) of the eluate from the Superdex S75 column is plotted as a function of time. For the principal peaks, the molecular weight (MW) of the species in the eluate is calculated from light-scattering measurements.
