Myoglobin binds oxygen and other ligands in human and vertebrate skeletal muscles and myocardium. Myoglobin is a monomeric 153–154 amino-acid globular protein that contains iron-heme and has a molecular weight of approximately 17 kilodaltons [1].

In 1958, myoglobin was the first protein to have its spatial structure solved by crystallographic methods [2], and this protein is often used as a model for testing and developing new methods for studying the spatial structure and dynamics of biomolecules [3].
