Aldose reductase-catalyzed reduction of aldehyde phospholipids.
Oxidation of unsaturated phospholipids results in the generation of aldehyde side chains that remain esterified to the phospholipid backbone. Such "core" aldehydes elicit immune responses and promote inflammation. However, the biochemical mechanisms by which phospholipid aldehydes are metabolized or detoxified are not well understood. In the studies reported here, we examined whether aldose red...
متن کاملPig muscle aldehyde reductase. Identity of pig muscle aldehyde reductase with pig lens aldose reductase and with the low Km aldehyde reductase of pig brain and pig kidney.
A monomeric (Mr = 43,000) NADPH-dependent oxidoreductase with a broad substrate specificity for aliphatic and aromatic aldehydes and aldo sugars has been purified from the skeletal muscle of female and castrated pigs. The properties of this enzyme are consistent with those of aldose reductase (EC 1.1.1.21), and the enzyme is immunologically identical with aldose reductase from pig lens. However...
متن کاملStructural features of the aldose reductase and aldehyde reductase inhibitor-binding sites.
The three-dimensional structures of aldose reductase and aldehyde reductase, members of the aldo-keto reductase superfamily, are composed of similar alpha/beta TIM-barrels. However, examination of the structures reveals that the inhibitor-binding site of aldose reductase differs from that of aldehyde reductase due to the participation of non-conserved residues in its formation. This information...
متن کاملPurification and Properties of an NADPH-Aldose Reductase (Aldehyde Reductase) from Euonymus japonica Leaves.
The enzyme aldose (aldehyde) reductase was partially purified (142-fold) and characterized from Euonymus japonica leaves. The reductase, a dimer, had an average molecular weight of 67,000 as determined by gel filtration on Sephadex G-100. The enzyme was NADPH specific and reduced a broad range of substrates including aldoses, aliphatic aldehydes, and aromatic aldehydes. Maximum activity was obs...
متن کاملMelatonin Reduces Cataract Formation and Aldose Reductase Activity in Lenses of Streptozotocin-induced Diabetic Rat
Background: The relationship between the high activity of aldose reductase (AR) and diabetic cataract formation has been previously investigated. The purpose of the present study was to determine the preventing effect of melatonin on streptozotocin (STZ)-induced diabetic cataract in rats.Methods: 34 adult healthy male Sprague-Dawely rats were divided into four groups. Diabetic control and diabe...
