Lactase

Lactase (or β-galactosidase) is the enzyme ({{EC number|3.2.1.23}}) involved in the hydrolysis of lactose to galactose and glucose. In humans, it is produced in the digestive tract. Deficiency of the enzyme causes lactose intolerance; most deficiency states are probably not due to defects in the lactase gene, but to mutations in the MCM6 gene.
