Yeast glucoamylases: molecular-genetic and structural characterization
Abstract: Glucoamylase is an extracellular enzyme produced mainly by microorganisms. It belongs to the commercially frequently exploited biocatalysts. The major application of glucoamylase is in the starch bioprocessing to produce glucose and in alcoholic fermentations of starchy materials. Filamentous fungi have been the source of glucoamylases for industrial purposes as well as an object of numerous research studies. Some yeasts also secrete a large amount of glucoamylase with biochemical characteristics slightly different from those of filamentous fungi. Modern biotechnological applications require glucoamylases of certain properties optimal for a given process. Novel biocatalysts can be prepared from already existing enzymes using techniques of protein engineering or directed evolution. Tailoring of a commercial glucoamylase requires knowledge, on a molecular level, of structure/function relationships of enzymes originating from various sources and having different catalytic properties. Sequences of the cloned genes, their recombinant expression and the tertiary structure determination of glucoamylase are prerequisite to obtain such information. The presented review focuses on molecular-genetic and structural aspects of yeast glucoamylases, supplemented with the basic biochemical characterization of the given enzymes.
