General description

Maltotetraose also known as Amylotetraose, is a tetrasaccharide that is composed of glucose molecules linked by α-1,4 glycosidic bonds and has been commonly found in B. stearothermophilus. It increases the α-amylase synthesis rate in B. stearothermophilus and inhibits TNF-α-induced expression of intercellular adhesion molecule-1 (ICAM-1). Maltotetraose can be used as a substrate for the enzyme-coupled determination of amylase activity in biological fluids that finds application in metabolomics and biochemical research.

Application

Maltotetraose producing amylases are highly desirable for application in bread making and other food industries. It has been used in a study to characterize an exo-acting intracellular a-amylase from the hyperthermophilic bacterium Thermotoga neapolitana.

Features and Benefits

  • High-purity compound suitable for a wide variety of research applications

Maltooligosaccharides especially maltotriose and maltotetraose producing amylases are highly desirable for application in bread making and other food industries. A maltotriose and maltotetraose producing amylase from moderately halophilic Marinobacter sp. EMB8 is described. Under optimized culture conditions, 48.0 IU/mL amylase

We cloned and expressed the gene for an intracellular alpha-amylase, designated AmyB, from the hyperthermophilic bacterium Thermotoga neapolitana in Escherichia coli. The putative intracellular amylolytic enzyme contained four regions that are highly conserved among glycoside hydrolase family (GH) 13 alpha-amylases.
