Application
Digalacturonic acid (DGA), derived in vivo from pectin catabolism, is used for the co-crystallization of enzymes such as proteinase K. It is used in galacturonic acid metabolism research as a substrate to identify, differentiate and characterized endo- and exopolygalacturonase(s) and gluconase(s). DGA is used to study the transport of oligogalacturonides by systems such as the TogMNAB ABC transporter.

Since enzymatic degradation is a mechanism or component of the aggressiveness of a pathogen, enzymatic activities from a Fusarium graminearum isolate obtained from infected wheat spikes of Argentina Pampa region were studied in order to understand the disease progression, tending

We isolated and characterized a new type of endopolygalacturonase (PG)-encoding gene, pgaD, from Aspergillus niger. The primary structure of PGD differs from that of other A. niger PGs by a 136 amino acid residues long N-terminal extension. Biochemical analysis demonstrated

The solution conformation of digalacturonic acid and its sodium salt have been analyzed using nuclear magnetic resonance data and molecular mechanics calculations. The flexibility around the glycosidic linkage was characterized by calculation of the relaxed (phi, psi) potential surfaces for

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
