Application

体内源自果胶分解代谢的二半乳糖醛酸(DGA)用于酶(例如蛋白酶K)的共结晶。它在半乳糖醛酸代谢研究中用作底物,以鉴定、区分和表征内聚和外聚半乳糖醛酸酶和葡萄糖酶。 DGA用于研究诸如TogMNAB ABC转运蛋白之类的系统对寡半乳糖醛酸的转运。

In Saccharomyces cerevisiae, an endopolygalacturonase encoded by the PGL1 gene catalyzes the random hydrolysis of the α-1,4 glycosidic linkages in polygalacturonic acid. To study the regulation of the PGL1 gene, we constructed a reporter vector containing the lacZ gene under

D-galacturonic acid is the most abundant component of pectin, one of the major polysaccharide constituents of plant cell walls. Galacturonic acid potentially is an important carbon source for microorganisms living on (decaying) plant material. A catabolic pathway was proposed in

The process of pectin depolymerization by pectate lyases and glycoside hydrolases produced by pectinolytic organisms, particularly the phytopathogens from the genus Erwinia, is reasonably well understood. Indeed each extracellular and intracellular catabolic stage has been identified using either genetic, bioinformatic
