The interaction of nitric oxide with soybean lipoxygenase-1

The interaction of nitric oxide with the non-heme iron dioxygenase lipoxygenase is reported. This apparently resulted in a novel type of complex where an electron is donated to the NO molecule. In addition a new position for an EPR transition from iron was discovered which, it is suggested results from high spin ferric iron in a field of axial symmetry characterised by a very low value for D.
