Allosteric modulation of monomeric proteins*

Abstract Multimeric proteins ( e.g. hemoglobin) are considered to be the prototypes of allosteric enzymes, whereas monomeric proteins ( e.g. myoglobin) usually are assumed to be nonallosteric. However, the modulation of the functional properties of monomeric proteins by heterotropic allosteric effec...

Description
Summary:Abstract Multimeric proteins ( e.g. hemoglobin) are considered to be the prototypes of allosteric enzymes, whereas monomeric proteins ( e.g. myoglobin) usually are assumed to be nonallosteric. However, the modulation of the functional properties of monomeric proteins by heterotropic allosteric effectors casts doubts on this assumption. Here, the allosteric properties of sperm whale myoglobin, human serum albumin, and human α‐thrombin, generally considered as molecular models of monomeric proteins, are summarized.
