Abstract
Enzymes from extremophiles, especially psychrophiles and psychrotolerant microorganisms are currently intensively studied because of their unusual structural and functional properties. One of these enzymes is a cold-adapted - galactosidase (EC 3.2.1.23) which catalyzes the hydrolysis of - 1,4-glycosidic bonds in -galactosides. The most common - galactoside is lactose, a disaccharide which makes up 2-7% of milk. The majority of adult people are lactose intolerant, which is an impulsion for the production of a low lactose milk with the use of -galactosidase. Among over twenty isolated enzymes with -galactosidase, the activity of nine was derived from a psychrotolerant bacteria of the Arthrobacter genus. These enzymes are members of three different glycoside hydrolases families: 2, 35 and 42.
