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.
A purified .alpha.-agarase which hydrolyzes the .alpha.-1,3 bond between the non-reducing terminal 3,6-anhydro-L-galactose and the adjacent D-galactose of neoagaro-oligosaccharides of six or fewer monosaccharide units and has the following physical and chemical characteristics:
A purified .alpha.-agarase which has the following physical and chemical characteristics:
A purified .alpha.-agarase from Vibrio sp. JT0107-L4.
