Human urinary amylolytic enzymes in acute hepatitis

Human urinary amylolytic enzymes in acute hepatitis.

Using paper eletrophoresis two amylolytic enzymes in human urine were demonstrated. A main peak was shown in the gamma globulin zone in normal urine and a second minor peak, in contrast to earlier findings, in the beta globulin zone. The organic source of the minor peak is probably in the liver. Urines from cases of acute hepatitis were studied in the same way and showed that the electrophoreti...

Amylolytic enzymes: molecular aspects of their properties.

The present review describes the structural features of alpha-amylase, beta-amylase and glucoamylase that are the best known amylolytic enzymes. Although they show similar function, i.e. catalysis of hydrolysis of alpha-glucosidic bonds in starch and related saccharides, they are quite different. alpha-Amylase is the alpha --> alpha retaining glycosidase (it uses the retaining mechanism), and b...

Determination of Glucoamylase in Culture Filtrates Ccontaining Other Amylolytic Enzymes

Bestimmung der Glucoamylase in Kulturfiltraten, die andere amylolytische Enzyme enthalten. Es wird eine verbesserte Methode fur die bestimmung der Glucoamylase in Gegenwart anderer amylolytischer Enzyme vorgeschlagen. Sie beruht auf der Verwendung von Dextran mit niedrigem Molekulargewicht als spezifisches Substrat. Die Bestimmung der aktivitat erfolgt durch quantitative Ermittlung der Glucosem...
