additional information	-	molecular reasons for the high intrinsic stability of the enzyme: the molecule is extremely rigid, even with respect to structural changes during substrate binding and turnover. Major contributions to the high intrinsic stability of the enzyme result from the formation of the dimer. Within the monomer, only subtle stabilizing interactions are detectable. The docking of the subunits is optimized with respect to high packing density in the dimer interface, additional salt-bridges and beta-sheets	Thermotoga maritima
