Avenacosidase is a glucosidase enzyme found in the oat species Avena. Avenacosidase is known to act against fungal infection. Avenacosidase is a member of the family of enzymes that catalyze the hydrolysis of O and S-glycosyl compounds. [1] [2] The enzyme catalyzes the following reaction:

avenacoside B + H2O = 26-desgluco-avenacoside B + D-glucose

The protein consists of 60 kDa (kilodalton) subunits, and was first isolated from oat seedlings. The enzyme is known to halt all catalytic activity once frozen and thawed. [3] [4]
