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...

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...

An electrophoretic transfer technique was developed for the specific identification of isozymes of starch debranching enzyme, alpha-amylase, and beta-amylase. Amylolytic enzymes are separated by native polyacrylamide slab gel electrophoresis and proteins in gels are electrophoretically transferred through starch-containing polyacrylamide gels. Each amylolytic enzyme degrades starch in the trans...

Amylases are starch degrading enzymes. They are widely distributed in microbial, plant and animal kingdoms (Banks et al, 1975). They degrade starch and related polymers to yield products characteristic of individual amylolytic enzymes. Initially the term amylase was used originally to designate enzymes capable of hydrolysing α-1, 4glycosidic bonds of amylose, amylopectin, glycogen and their deg...

Amylolytic bacteria have great genetic diversity with high enzymatic activity and the expertise to break down starch into simpler materials degrade organic substances in water. This study aims determine variety of types amylolytic obtained see how characterization is isolated from waters Paris Tigaras Beach.

To isolate novel and useful microbial enzymes from uncultured gastrointestinal microorganisms, a fecal microbial metagenomic library of the pygmy loris was constructed. The library was screened for amylolytic activity, and 8 of 50,000 recombinant clones showed amylolytic activity. Subcloning and sequence analysis of a positive clone led to the identification a novel gene (amyPL) coding for α-am...
