The present invention relates to a method for preparing neoagarotetraose and neoagarohexaose, and specifically, by reacting agarose with DagA protein derived from Streptomyces coelicolor A3 (2), agarose The present invention relates to a method for preparing agarotetraose and neoagarohexaose. According to the present invention, when agarose or agar is decomposed using agarase derived from Streptomyces cyricolor, neoagarotetraose and neoagarohexaose can be efficiently produced, and the optimum conditions according to the present invention are applied. If you do more efficient manufacturing is possible. In addition, since the preparation method according to the present invention is a method using an enzyme rather than a chemical method, it is environmentally friendly and has fewer side effects on the human body of the prepared oligosaccharide, which can be usefully used in the food, cosmetics, and pharmaceutical industries. |
