The yellow form of soybean lipoxygenase-1 (linoleate:oxygen oxidoreductase, EC 1.13.11.12), obtained upon addition of one molar equivalent of 13-ls-hydroperoxy-9-cis,11-trans-octadecadienoic acid (13-l-HPOD) to the native enzyme, shows a complex EPR

(1) The magnetic susceptibility of native soybean lipoxygenase-1, a non-heme iron dioxygenase, has been measured over the temperature range 10–170 K. (2) With the ground-state multiplet of its high-spin Fe(II) described by means of a spin Hamiltoni

The line-shape of the EPR signal around g 6 of yellow lipoxygenase-1, obtained upon addition of I molar equivalent of 13-,11-trans-octadecadienoic acid to the native enzyme (linoleate:oxygen oxidoreductase, EC 1.13.11.12), is strongly affected by alc

The question of dioxygen coordination to iron in soybean lipoxygenase (linoleate:oxygen oxidoreductase, EC 1.13.11.12) has been investigated by EPR spectroscopy. EPR data in combination with magnetic susceptibility measurements on both air-saturated

The interaction of soybean lipoxygenase-1 with 13-Ls-hydroperoxy-9-cis,11-trans-octadecadienoic acid, the product of the enzymic dioxygenation of linoleic acid, results in the formation of either a yellow or a purple coloured enzyme form depending on

Measurements of the magnetic susceptibility of native lipoxygenase-1 yielded a value for the effective Bohr magneton number, n eff , equal to 5.2 which is characteristic for iron in high-spin Fe(II) state. Upon addition of native lipoxygenase-1 to a

The optical absorbance changes at 370 nm observed upon additon of 13- l s - hydroxyperoxy -9-cis,11-trans- octadecadienoic acid (13- l -HPOD) to native lipoxygenase-1 are linearly correlated to the amount of Fe(III) iron visible in the EPR signal aro

Lipoxygenases (linoleate:oxygen oxidoreductase EC 1.13.11.12) catalyze the dioxygenation of polyunsaturated fatty acids which posses a 1,4-cis,cis-pentadiene system. Under optimum conditions regarding pH, temperature, and concentration of the reactan

The zero-field splitting constants ( D ) of the different components building up the high-spin Fe(III) EPR spectrum of lipoxygenase from soybeans were determined by two methods: (1) temperature dependence studies using the low-spin Fe(III) signal of
