Figure 1

Schematic representation of the SlpB protein and sequence alignment of different S-layer proteins. In the schematic drawing of the S-layer protein SlpB comprising 440 amino acids, the signal sequence (SS) as well as the cell wall anchor are indicated. As demonstrated by multiple sequence alignment, the sequences of the C-terminally located cell wall anchor regions from the S-layer proteins SlpB of Lb. crispatus K2-4-3, S_A of Lb. acidophilus ATCC 4356 and CbsA of Lb. crispatus JCM 5810 showed high identity.
