Table 4 Divergence patterns in tteRBP and ecRBP. Classification of amino acids into core, boundary, or surface [37] allows identification of the regions which are conserved among tteRBP and ecRBP.

From: The backbone structure of the thermophilic Thermoanaerobacter tengcongensis ribose binding protein is essentially identical to its mesophilic E. coli homolog
