Sigma Aldrich - D4288

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