Descripción general

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in starch ethanol research. For more information see the article in biofiles.

Aplicación

Maltogenic amylases (MAse) are commonly used in the starch industry. They are used to hydrolyze starch, pullulan and cyclodextrin and to make novel carbohydrates .

Acciones bioquímicas o fisiológicas

Maltogenic amylase is in the amylolytic enzyme subfamily, which also consists of cyclomaltodextrinase, neopullulanase, and Thermoactinomyces vulgaris amylase II. These enzymes transfer the hydrolyzed sugar moiety to another sugar molecule. They have an (α/β)8 barrel and C domain as well as a 124-residue N domain, which is involved in homodimer formation .

Maltogenic amylases belong to a subclass of cyclodextrin-hydrolyzing enzymes and hydrolyze cyclodextrins more efficiently than starch unlike typical α-amylases. Several bacterial malto-genic amylases with temperature optima of 40-60°C have been previously characterized. The thermo-adaption, substrate preferences and transglycosylation aspects of

A gene encoding a hyperthermostable maltogenic amylase of Staphylothermus marinus (SMMA) was cloned and overexpressed in Escherichia coli. SMMA consisted of 696 amino acids with a predicted molecular mass of 82.5 kDa. The enzyme was active in acidic conditions (pH

The thermostability of maltogenic amylase from Thermus sp. strain IM6501 (ThMA) was improved greatly by random mutagenesis using DNA shuffling. Four rounds of DNA shuffling and subsequent recombination of the mutations produced the highly thermostable mutant enzyme ThMA-DM, which had

The goal of this study was to develop a maltose-producing enzyme using protein engineering and to clarify the relation between the substrate specificity and the structure of the substrate-binding site of dimeric maltogenic amylase isolated from Thermus (ThMA). Ala290 at

Ascorbic acid (1), a natural antioxidant, was modified by employing transglycosylation activity of Bacillus stearothermophilus maltogenic amylase with maltotriose and acarbose as donor molecules to enhance its oxidative stability. The transglycosylation reaction with maltotriose as donor created mono- and di-glycosyl
