  • Publication number: 20040024228
    Abstract: A process of the present invention produces a hydroxylactone by subjecting an unsaturated carboxylic acid having a double bond not conjugated to a carboxyl group or an ester thereof to (i) a reaction with hydrogen peroxide in the presence of a metallic compound containing a metallic element selected from W, Mo, V and Mn or (ii) a reaction with a peroxide containing the metallic element to thereby yield a corresponding hydroxylactone having a hydroxyl group combined with one of carbon atoms constituting the double bond and being cyclized at the other carbon atom position. The metallic compound may be one selected from oxides, oxoacids and salts thereof. The unsaturated carboxylic acid includes, for example, &bgr;,&ggr;-unsaturated carboxylic acids, &ggr;,&dgr;-unsaturated carboxylic acids, and &dgr;,&egr;-unsaturated carboxylic acids. The process can produce hydroxylactones in high yields at low cost.

  • Patent number: 5880272
    Abstract: An oxidized phospholipid degrading enzyme is provided, which plays an important role in the oxygen stress preventive mechanism in organisms. The enzyme hydrolyzes a 1-acyl-2-.omega.-carboxyfatty acid acyl-3-phosphatidylcholine as a substrate at the 2-ester bond thereof to form 1-acyl-2-lyso-3-phosphatidylcholine. The activity of the enzyme is slightly enhanced by 4 mM calcium chloride. The molecular mass of the enzyme is 95.+-.5 kDa (by gel filtration). The enzyme is composed of three subunits whose molecular masses have been found to be 29 kDa, 30 kDa and 45 kDa, respectively, by SDS-polyacrylamide electrophoresis. A gene coding the enzyme is also provided. This gene is important for the synthesis of the enzyme by genetic engineering.
