Globins are a family of oxygen-binding proteins built around a heme cofactor. They include hemoglobin, myoglobin, and neuroglobin, and are responsible for transporting and storing O₂ across nearly every vertebrate species.

Human deoxyhemoglobin in the tense T state. Pairs naturally with 1HHO to study the allosteric switch behind cooperative oxygen binding.
The first protein structure ever solved by X-ray crystallography (Kendrew, 1958). Still a benchmark for oxygen-storage dynamics.
