Crystal Structure of myoglobin, 1a6m

The heme group and oxygen binding in myoglobin.

Myoglobin is a protein whose function is to store oxygen in muscle tissues. Like heamoglobin, it is red in colour, and it is myoglobin that gives muscle its strong red colour.

Myoglobin was the first globular protein for which the 3-dimensional structure was solved, back in the late 1950s. It gives its name to the 'globin fold', a common alpha domain motif. An alpha domain is a structural region composed entirley of alpha-helix.
