Protein
Alpha-galacturonidase
Organism
Thermoanaerobacter italicus (strain DSM 9252 / Ab9)
Function
Alpha-galacturonidase able to catalyze the hydrolysis of the chromogenic substrate p-nitrophenyl-alpha-D-galacturonic acid (pNPalphaGalUA). It is probable that alpha-1,4-di-galacturonate (GalUA(2)) is the naturally occurring substrate.
Similarity
Belongs to the glycosyl hydrolase 4 family.
