The crystal structure of TATA binding protein (TBP) from a mesothermophilic archaeon, Sulfolobus acidocaldarius, has been determined at a resolution of 2.0 A with an R factor of 20.9%. By comparing this structure with the structures of TBPs from a hyperthermophilic archaeon and mesophilic eukaryotes, as well as by comparing amino acid sequences of TBPs from archaea, covering a wide range of optimum growth temperatures, two significant determinants of the stability of TBP have been identified: increasing the interior hydrophobicity by interaction between three residues, Val, Leu, and Ile, with further differentiation of the surface, and increasing its hydrophilicity and raising the cost of unfolding ...
