This coordination is called the 2-histidine-1-glutamate facial triad iron coordination and is seen in many mononuclear non-heme iron(II)enzymes<ref>PMID: 15739104</ref>. In this structure Glu317 coordinates the iron in a partial bidentate manner. The more common <scene name='User:Michael_Skovbo_Windahl/sandbox/1mlw_iron_coordination/3'>octahedral iron coordination</scene> (the resting state) for the 2-His-1-Glu iron coordination is seen in the structure of human TPH1 ([[1mlw]]).
