    摘要： The present invention aims to provide a fucose-binding protein that shows improved productivity in cases of expression in a host such as Escherichia coli, improved binding affinity to a fucose-containing sugar chain such as a sugar chain containing a structure composed of Fucα1-2Galβ1-3GlcNAc and/or Fucα1-2Galβ1-3GalNAc, and/or improved thermal stability. The above object is achieved by deleting a plurality of amino acid residues in the C-terminal side of the amino acid sequence of the fucose-binding protein BC2LCN of SEQ ID NO: 1, and, when necessary, substituting the glycine residue at position 36 in SEQ ID NO: 1 with a cysteine residue, substituting the glutamine residue at position 39 in SEQ ID NO: 1 with a leucine residue or methionine residue, substituting the glutamine residue at position 65 in SEQ ID NO: 1 with a leucine residue, substituting the cysteine residue at position 72 in SEQ ID NO: 1 with a glycine residue or alanine residue, substituting the glutamic acid residue at position 81 in SEQ ID NO: 1 with a cysteine residue, glutamine residue, histidine residue, or methionine residue, and/or substituting the glycine residue identified as the residue at position 36 in SEQ ID NO: 1 with a cysteine residue.

    摘要： Provided is a β-zeolite that has an SiO 2 /Al 2 O 3 ratio of less than 20 but yet is comparable or superior in heat resistance to conventional β-zeolites having SiO 2 /Al 2 O 3 ratio of 20 or greater. This β-zeolite is characterized in that: in powder X-ray diffractometry using a CuKα-ray as a ray source, the full width at half maximum of a powder X-ray diffraction peak on the (302) plane is 0.15-0.50 inclusive; and the molar ratio of silica to alumina is less than 20.0. Preferably, the β-zeolite is obtained by a production method which comprises a crystallization step for crystallizing a composition comprising an alumina source, a silica source, an alkali source, a tetraethylammonium cation source and water, characterized in that the composition contains potassium and the molar ratio of potassium to silica exceeds 0.04.
