Aspects of Enzymes

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...

Hydrolytic enzymes in Paracoccidioides brasiliensis--ecological aspects.

Paracoccidioides brasiliensis is a thermally dimorphic fungus that causes paracoccidioidomycosis. The yeast form of this pathogen is found in the animal host whereas the mycelial form is recovered from living and non-living organic material. The sole carbon source available in these habitats is represented by polysaccharides from the plant cell wall. Hydrolytic enzymes are necessary to convert ...

Structural and regulatory aspects of enzymes in chemotherapy.

A brief discussion is presented on the enzymatic changes in normal and malignant tissues after creation of metabolic stresses with Methotrexate and 6-azauridine. The possible relationship of these changes to the relative adaptive capabilities seen in normal liver and hepatomas as reported by Pitot and Potter is considered. Certain aspects of cell membrane structure and metabolism as they may re...
