Isolation of a third isoenzyme of soybean lipoxygenase.
نویسندگان
چکیده
I. A third isoenzyme of soybean lipoxygenase (linoleate: oxygen oxidoreductase, EC 1.13.I.13) has been purified to essential homogeneity by Sephadex DEAEA5o column chromatography and isoelectric focusing. 2. The enzyme differs from the two previously described pure isoenzymes (lipoxygenases-i and -2) 1 by the following criteria: elution profile from DEAESephadex, isoelectric point, pH activity profile, and the effect of Ca 2+ on activity. 3. The new isoenzyme also shows an anomalous, inverse dependence of activity on enzyme concentration.

The present work examines leaching of lipoxygenase-1 from soybean flour employing stirred tank vessel. The effect of operating parameters, impellers speed, operational period, temperature, pH and scale-up were considered.The acetic acid pH: 5.2 increased the leaching of lipoxygenase- 1.The sensitivity of agitator speed and geometrical-scale-up on the enzymeleaching has bee...
متن کاملLipoxygenase isoenzymes: a spectroscopic and structural characterization of soybean seed enzymes.
Applying recent developments in protein purification techniques, a number of lipoxygenase isoenzymes have been isolated in satisfactory quantities for a detailed physical and structural characterization. Four seed isoenzymes from two soybean cultivars have been studied by peptide mapping, free thiol and iron content determinations, and C-terminal analysis as well as by uv-visible absorption and...

Objective(s): Recently we reported that the soybean 15-lipoxygenase (SLO) inhibitory activity of pyrimido[4,5-b][l,4]benzothiazines largely depends on the orientation of sulfur atom of thiazine core towards FeIII-OH in the active site pocket of the enzyme with subsequent oxidation of sulfur to sulfoxide. In this paper the results of a comparative study on the SLO inhibitory activities of the ...

Objective(s): 15-Lipoxygenases are one of the iron-containing proteins capable of performing peroxidation of unsaturated fatty acids in animals and plants. The critical role of enzymes in the formation of inflammations, sensitivities, and some cancers has been demonstrated in mammals. The importance of enzymes has led to the development of mechanistic studies, product analysis, and synthesis of ...
متن کاملCrystallization and preliminary X-ray characterization of a soybean seed lipoxygenase.
An isoenzyme of soybean (Glycine max L. Merrill cv. Provar) lipoxygenase (EC 1.13.11.12) has been crystallized using the vapor diffusion method. Crystals were grown from solutions of the protein (7 mg/ml) using 10 to 20% (w/v) polyethylene glycol 8000 in citrate/phosphate buffer (pH 5.7) containing 0.5% (w/v) n-octyl-beta-D-glucopyranoside. The crystals reached maximum dimensions of 0.3 mm x 0....
