    摘要： The present inventions relate to novel .alpha.-agarase which selectively hydrolyzes the 1,3-bond of an oligosaccharide derived from agarose; a process for producing oligosaccharides and/or monosaccharides, characterized by that a .beta.-agarase which acts on both polysaccharides and oligosaccharides derived from agarose and an .alpha.-agarase which acts specifically on oligosaccharides derived from agarose are allowed to react with a substrate which contains agarose or an oligosaccharide derived from agarose; and a process for producing oligosaccharides and/or monosaccharides, characterized by that the above .alpha.-agarase is allowed to react with a substrate which contains an oligosaccharide derived from agarose.

    摘要： This invention relates to an agarase enzyme system purified from bacterial strain 2-40, which has a high level of activity for the depolymerization of complex polysaccharides, including agar and agarose. Further, the invention relates to methods of purifying, defining, characterizing and assaying the agarase enzyme system and the encoding gene(s). Finally, the invention relates to methods of using the purified agarase enzyme system.
