Christian Bohr. Discoverer of Homotropic and Heterotopic Allostery

Acta Physiologica, Volume 241, Issue S734, July 2025.
ABSTRACT This essay recounts and revisits the scientific contributions of Christian Bohr, highlighting his pivotal role in discovering allostery about 120 years ago. Bohr's meticulous experimentation led to identifying two distinct forms of allostery: homotropic (single‐ligand) and heterotropic (multi‐ligand), the latter widely recognized as the Bohr ...
