Allosteric enzymes as models for chemomechanical energy transducing assemblies

Goldsmith, Elizabeth J.·1996·The FASEB Journal

Abstract

In chemomechanical energy transducing assemblies such as muscle and ATP synthase, substrates and macromolecules are locked together as partners where energy available from (or required for) a chemical transformation is exchanged with protein conformational changes. Allosteric binding proteins and enzymes are also chemomechanical energy transducers, using binding energy to generate protein conformational changes, and transduce energy in amounts almost as large as those used to drive muscle contraction and the synthesis of ATP. The recently determined structure of the F1‐ATPase reveals a direct correspondence between the types of conformational changes in this transducer and simpler allosteric binding proteins and enzymes. Therefore, we can examine the structural and energetic data available on allosteric proteins to understand the linkage between ligand binding and global conformational changes in more complex energy transducing assemblies.—Goldsmith, E.

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.
