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 6

Primary amino acid alignment of the three major Methanosarcina S-layer proteins, Mbar_A1758, MA0829, and MM1976. Identity of the sequences is indicated by asterisks. The experimentally determined mature N-terminus for Mbar_A1758 (Section 3) is indicated by the arrow.
