'''NAPHTHALENE 1,2-DIOXYGENASE WITH NAPHTHALENE BOUND IN THE ACTIVE SITE.'''
===NAPHTHALENE 1,2-DIOXYGENASE WITH NAPHTHALENE BOUND IN THE ACTIVE SITE.===




==Overview==
<!--
Binding of oxygen to iron is exploited in several biological and chemical processes. Although computational and spectroscopic results have suggested side-on binding, only end-on binding of oxygen to iron has been observed in crystal structures. We have determined structures of naphthalene dioxygenase that show a molecular oxygen species bound to the mononuclear iron in a side-on fashion. In a complex with substrate and dioxygen, the dioxygen molecule is lined up for an attack on the double bond of the aromatic substrate. The structures reported here provide the basis for a reaction mechanism and for the high stereospecificity of the reaction catalyzed by naphthalene dioxygenase.
The line below this paragraph, {{ABSTRACT_PUBMED_12586937}}, adds the Publication Abstract to the page
