Multiple-sequence alignment of the SLH module of A. cellulolyticus ScaC (Acece-ScaC) and the three C. thermocellum anchoring proteins (Clotm-OlpA, Clotm-OlpB, and Clotm-Orf2p). The degrees of conservation are indicated as follows: asterisks indicate that all sequences are identical, colons indicate that the residues are conserved, and dots indicate that residues are semiconserved, as defined by the EBI server (http://www2.ebi.ac.uk/clustalw/).
