'''PROXIMAL AND DISTAL HISTIDINES''': The iron atom sits either side of the side chains of two <scene name='User:Michael_Roberts/BIOL115_Myo/Heme/4'>histidine residues</scene>.
 
The iron atom sits either side of the side chains of two <scene name='User:Michael_Roberts/BIOL115_Myo/Heme/4'>histidine residues</scene>.
One of these (coloured cyan) is attached to the iron atom, and is known as the ''proximal'' histidine. The other (green) is called the ''distal'' histidine.
