Glucan 1,3-β-glucosidase (, ''exo-1,3-β-glucosidase'', ''β-1,3-glucan exo-hydrolase'', ''exo (1→3)-glucanohydrolase'', ''1,3-β-glucan glucohydrolase'') is an

enzyme An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different mol ...
