Isolation of human renin inhibitor from soybean: soyasaponin I is the novel human renin inhibitor in soybean.
We found human renin inhibitory activity in soybean and isolated the active compound, soybean renin inhibitor (SRI). The physico-chemical data on the isolated SRI were identical with those of soyasaponin I. SRI showed significant inhibition against recombinant human renin, with an IC(50) value of 30 microg/ml. Kinetic studies with SRI indicated partial noncompetitive inhibition, with a K(i) val...

Glycolate oxidase content of microbodies as affected by nitrate.
Glycolate oxidase is loosely held by microbodies obtained from etiolated barley (Hordeum vulgare L.) leaves depleted of nitrate. Defined centrifugation conditions cause the complete detachment of the enzyme from the microbodies. Addition of nitrate to these plants brings about a greater retention of glycolate oxidase by the microbodies. Synthesis of a nitrate-induced protein seems to be respons...
متن کاملOnion, a Potent Inhibitor of Xantine Oxidase
Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...
متن کاملGlycolate oxidase activity in algae.
The g1lycolate oxidase reactioni by x-hich gly colate is oxidized to glyoxylate (3, 10) is catailyzed by a flavoprotein (18) th,at is widely distributed in higher plants (12) and fungi (4). Its presence is g,elleralllly assumed in all phoiosynithetic tissuies, since glycolate is an early product of photosynthesis (14), yet this substrate is tusually found in oiily minute amounits. The oxidation...
