FIG. 5.

Alignment of the signature sequences of cluster 1 binding proteins with TMBP of T. litoralis. The different amino acids possible for each position are indicated below the signature sequence. Numbers in parentheses indicate positions. The highly conserved lysine residue (K) is boxed. Residues of T. litoralis that match the signature sequence are in boldface, and residues conserved in other sequences are underlined. The signature sequence is from reference 48. Tl, T. litoralis; Ec, E. coli (16); St, Salmonella typhimurium (12); Sp, S. pneumoniae (39); Tt, T. thermosulfurigenes (41); MalE, MalX, and AmyE, maltose/maltodextrin-binding proteins; UgpB (35), glycerol-3-phosphate-binding protein.
