Plasma concentration, renal and faecal excretion, absorption and metabolism of the tritiated beta-adrenergic blocker Kö 592 were studied in man, dog and rat. The substance was absorbed to an extent of 90–100% in all species (rat within 30 min, dog within 80 min, man within 120 min). The half-life of radio-activity in the plasma was 3 h in man and dog, in(More)
In addition to our previous paper [1] further characteristics of the chlorogenic acid hydrolase are described. Polyacrylamide gel electrophoresis revealed only one band for the purified enzyme. Sodium dodecyl-sulfate polyacrylamide gel electrophoresis showed a molecular weight of 60 000, demonstrating four subunits of the enzyme (total molecular weight 240(More)
The isolation and characterization of a specific chlorogenic acid esterase is described. The enzyme activity is measured by determination of the hydrolysis product caffeic acid. The enzyme had been concentrated by means of ultrafiltration and column-chromatography. The pH- and temperature optimum were 6.5 and 45 degrees C respectively. Divalent cations were(More)
Large, infrequent natural disturbances have been proposed as a key component in determining the distribution and abundance of Nothofagus in southern Andean temperate forests. In this study, a comparison of influences of small-to-intermediate-sized natural disturbances and effects of selective logging on the establishment and growth of Nothofagus forests in(More)
The characteristic features of an acetic acid esters hydrolyzing enzyme (acetylesterase, EC 3.1.1.16) are described. The pH- and temperature optimum were 7.0 and 40 degrees C respectively. The stability of the enzyme regarding different pH- and temperature conditions was investigated. The molecular weight of the acetylesterase could be determined to 160(More)
