Method P.1 right column bottom paragraph:"Here, [investigators] jointly address the rate–temperature dependencies of all enzyme classes, and compare them to the dependency of nonenzymatic reactions. [They] challenge the generally accepted paradigm that thermophilic, mesophilic, and psychrophilic enzymes have distinct rate–temperature dependencies, and that temperature–rate dependencies relate, by default, to enzyme dynamics. [They] suggest a common theme that underlines the temperature–rate dependency of all enzymes as long as they maintain their folded state. Also, [they] re-examine the generally assumed linkage between the overall rigidity of the fold and active site of an enzyme."
Comments P.2 left column 2nd paragraph:"Rate–temperature dependencies are compared using the empirical measure of Q10 (Box 1). [Investigators] systematically explored the existing literature, and extracted Q10 values for >150 enzymatic reactions from the three environmental classes, including reactions for which Q10 values were available for both the enzymatic and nonenzymatic reactions (Figure 1 Text S1 and Tables S1–S4 in the supplementary material online)."
