Description

technical field

[0001] The invention relates to a trehalose synthase and its application. Background technique

[0002] Trehalose (Trehalose) molecule is composed of two glucopyranose linked by 1,1-glycosidic bond, there is no free hemi-condensed hydroxyl group in the molecule, it is a stable non-reducing disaccharide. There are three optical isomers of trehalose, among which αβ type (Neotrehalose, new trehalose) and ββ type (Isotrehalose, different trehalose) rarely exist in nature, and αα type is the most common trehalose (also known as mushroom Sugar), widely present in bacteria, fungi, algae, lower plants and insects.

[0003] Trehalose is colorless and odorless, has strong thermal stability, acid stability and chemical stability, and has a strong stabilizing effect on living components such as proteins, nucleic acids, and cell membranes. Trehalose is usually used as a Compatibility medium protects biomacromolecules and even organisms. Studies have shown that trehalos...
