Genome mining for glycoside hydrolases from the psychrophilic yeast Glaciozyma antarctica PI12

Glycoside hydrolases are enzymes that hydrolyse glycosidic bonds in carbohydrate chains to produce simple molecules. In fungi, glycoside hydrolases are important enzymes that hydrolyse complex carbohydrates into simple sugars that can subsequently be consumed for energy metabolism. Glaciozyma anta...
