Documentation of the purification procedure. (a) SDS–PAGE separations of samples representing whole cell extracts (WCE), the soluble fraction after lysate clearance by ultracentrifugation and fractions of elution from immobilized metal-chelating chromatography. Lane M contains molecular-weight marker (labelled in kDa). (b) After pooling and concentration, the sample was further separated by size-exclusion chromatography on a Superose 6 10/300 column. The elution profiles of globular markers of the indicated molecular mass are shown. The elution profile and corresponding protein content are shown. The lanes marked L contain two concentrations of sample loaded onto the column. Lane M contains molecular-weight marker (labelled in kDa).
