alpha,alpha-trehalase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: alpha,alpha-trehalose + H2O = 2 D-glucose. [PMID:19897915, RHEA:32675]

Alpha,alpha-trehalase activity is a hydrolytic enzyme activity that catalyzes the breakdown of the disaccharide trehalose into two glucose molecules. Trehalose is a non-reducing sugar that is found in a variety of organisms, including bacteria, fungi, insects, and plants. In these organisms, trehalose plays a number of important roles, including serving as a storage form of energy, protecting cells from stress, and aiding in the stabilization of proteins. Alpha,alpha-trehalase is involved in the breakdown of trehalose, releasing glucose that can be used for energy or other metabolic processes. The enzyme specifically hydrolyzes the alpha,alpha-1,1-glycosidic bond between the two glucose molecules in trehalose. This activity is crucial for the mobilization of trehalose reserves and is also involved in various physiological processes, such as trehalose degradation during starvation or stress conditions. The activity of alpha,alpha-trehalase is tightly regulated in different organisms, ensuring that trehalose breakdown occurs when it is needed.'
