α-Amylases are hydrolytic enzymes responsible for the mobilization of the starch into metabolizable sugars. This process provides the energy for the growth of roots and shoots and is crucial during germination of cereal seeds.These enzymes are coded by a multigene family and even thought other amylolytic enzyme participate in the process of starch breakdown, the contribution of α-amylase is the prerequisite for the initiation of this process.
