The present invention relates to a method for preparing 3,6-anhydro-L-galactose, and use thereof. More specifically, 3,6-anhydro-L-galactose, which is a monosaccharide constituting agar, is produced in a high yield through chemical and enzymatic methods, and the physiological activities thereof such as whitening, moisturizing, antioxidant, anti-inflammatory activities and the like are displayed, thereby enabling industrial use thereof.

Provided are novel &#x3b1;-neoagarobiose hydrolase and a method for obtaining a monosaccharide using the same.

Alpha-neoagarobiose hydrolase and method for obtaining a monosaccharide using same

Disclosed is a novel marine microorganism which can metabolize 3,6-anhydro-L-galactose and use of the same. The novel marine microorganism belongs tosp. which utilizes 3,6-anhydro-L-galactose (3,6-L-AHG) as a single carbon source to convert 3,6-L-AHG to ribose and 3,6-anhydrogalactonic acid.

Marine bacterium of metabolizing 3,6-anhydro-L-galactose and use of the same

An isolated polypeptide is disclosed that improves the hydrolyzing capacity of a polysaccharide hydrolase such as cellulase, is capable of binding to a polysaccharide, is deficient in polysaccharide hydrolase activity, and includes a GH45 or a pollen-allergen domain. Methods of hydrolyzing polysaccharides using the isolated polypeptide are also disclosed.

Isolated polypeptide for increasing activity of polysaccharide hydrolase and methods of use

Provided herein are a composition for measuring 3,6-anhydro-L-galactose (3,6-L-AHG) transferase activity by reduction of NADP to NADPH, and a method of measuring 3,6-L-AHG transferase activity using the same. The composition and method are useful for determining 3,6-L-AHG in a material containing 3,6-L-AHG such as algae biomass and industrial applications.

Compositions and methods for measuring 3,6-L-AHG transferase activity and 3,6-L-AHG

Gene sequences of superoxide dismutase of Aquifex pyrophilus which is one of hyperthermophile microorganism and protein expressed therefrom are provided, wherein the protein is used as a necessary medicament in treatment of inflammation, disease of autoimmunization, chromosome lesion and the like, and particularly, A. pyrophilus is a hyperthermophile which can grow at the optimum temperature of 85.degree. C., and thus the superoxide dismutase of A. pyrophilus has a higher thermal stability than other organisms, resulting in further broad applications in the pharmaceutical field.
