LIPOXYGENASE-3(SOYBEAN) NON-HEME FE(II) METALLOPROTEIN
Overview
Soybean lipoxygenase isoenzyme L3 represents a second example (after L1), of the X-ray structure (R = 17% at 2.6 A resolution) for a member of the, large family of lipoxygenases. L1 and L3 have different characteristics in, catalysis, although they share 72% sequence identity (the changes impact, 255 amino acids) and similar folding (average C alpha rms deviation of 1, A). The critical nonheme iron site has the same features as for L1:3O and, 3N in pseudo C3v orientation, with two oxygen atoms (from Asn713 and, water) at a nonbinding distance. Asn713 and His518 are strategically, located at the junction of three cavities connecting the iron site with, the molecule surface. The most visible differences between L1 and L3, isoenzymes occur in and near these cavities, affecting their ... [(full description)]
