Identification of the Major Expressed S-Layer and Cell Surface-Layer-Related Proteins in the Model Methanogenic Archaea: Methanosarcina barkeri Fusaro and Methanosarcina acetivorans C2A

Figure 1

Fractionation of M. barkeri cell proteins by SDS-PAGE. (a) Pro-Q Emerald glycoprotein-stained gel. Lanes: G: glycoprotein standards; L: whole-cell lysate. Gel bands analyzed by LC-MS/MS are numbered. (b) SYPRO-Ruby-stained gel. Lanes: G: glycoprotein standards; L: whole-cell lysate; M: protein standard set 2. Protein sizes are indicated in kDa. The indicated bands 1–6 were excised for LC-MS/MS analysis.
