FIG. 5.
SDS-PAGE patterns of the S-layer protein from B. stearothermophilus PV72/p2 degraded with endoproteinase Glu-C in 2 M GHCl in the absence (a) and in the presence (b) of the SCWP. (c) The S-layer protein kept in the water-soluble state after GHCl was removed by dialysis due to the presence of SCWP (250 μg/mg of S-layer protein). Molecular size is indicated in kilodaltons.
