Biochemical properties

Glycoside hydrolase family 15 comprises enzymes with several known activities: glucoamylase, α-glucosidase, and glucodextranase. Glucoamylase catalyzes the release of D-glucose from the non-reducing ends of starch and other oligo or polysaccharides. This family also includes phosphorylase b kinase, which catalyzes the phosphorylation of serine in certain substrates, such as troponin I.

Allergens from this family

Fungal glucoamylases were identified as minor allergen in Apergillus niger [1] and as major allergen in Schizophyllum commune [2].
