Why Enzymes Are Proficient Catalysts: Beyond the Pauling Paradigm
Abstract
Pauling proposed that "enzymes are molecules that are complementary in structure to the activated complexes of the reactions that they catalyze, ..., [rather than] entering into reactions". This paradigm has dominated thinking in the field. While complementarity of the type proposed by Pauling can account for acceleration up to 11 orders of magnitude, most enzymes exceed that proficiency. Enzymes with proficiencies ((k(cat)/K(M))/k(uncat)) > 10(11) M(-1) achieve over 15 kcal/mol of "transition state binding" not merely by a concatenation of noncovalent effects but by covalent bond formation between enzyme or cofactor and transition state, involving a change in mechanism from that in aqueous solution. Enzymes enter into reactions with substrates and do not merely complement the transition states of the uncatalyzed reactions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
