Usage

General Description

Laminaritetraose is a natural, water-soluble polysaccharide that is composed of four glucose units linked together in a linear fashion. It is commonly found in brown seaweeds and serves as a structural component of their cell walls. Laminaritetraose has gained attention in the fields of food science and biotechnology due to its potential health benefits, such as its prebiotic properties that support the growth of beneficial gut bacteria. It also has potential applications in the development of functional foods, pharmaceuticals, and as a renewable source of biofuel. Studies have shown that laminaritetraose has anti-inflammatory and antioxidant properties, making it a promising candidate for various applications in the health and biotechnology industries.

Purification and characterization of 1,3-β-D-glucan phosphorylase from Ochromonas danica

1,3-β-D-Glucan phosphorylase (BGP) is an enzyme that catalyzes the reversible phosphorolysis of 1,3-β- glucosidic linkages to form α-D-glucose 1-phosphate (G1P). Here we report on the purification and characterization of BGP from Ochromonas danica (OdBGP). The purified enzyme preparation showed three bands (113, 118, and 124 kDa) on SDS-polyacrylamide gel electrophoresis. The optimum pH and temperature were 5.5 and 25°C-30°C. OdBGP phosphorolysed laminaritriose, larger laminarioligosaccharides, and laminarin, but not laminaribiose. In the synthesis reaction, laminarin and laminarioligosaccharides served as good acceptors, but OdBGP did not act on glucose. Kinetic analysis indicated that the phosphorolysis reaction of OdBGP follows a sequential Bi Bi mechanism. The equilibrium of the enzymatic reaction indicated that OdBGP favors the reaction in the synthetic direction. Overnight incubation of OdBGP with laminaribiose and G1P resulted in the formation of precipitates, which were probably 1,3-β-glucans.
