Masahiro Nakajima received his Ph.D. from the Graduate School of Agricultural and Life Science, The University of Tokyo in 2006. He joined the group of Dr. Motomitsu Kitaoka as a postdoctoral fellow (2006-2010). He moved to Iwate Biotechnology Research Center as a researcher (2010-2012). He is an assistant professor in Taguchi Laboratory at Department of Applied Biological Science, Tokyo University of Science (2012-). His research currently focuses on structures and functions of carbohydrate-active enzymes acting on unique sugar chains such as β-1,2-glucan. He acts as a Responsible Curator of Glycoside Hydrolase Families GH144 and GH162. He determined the functions and/or crystal structures of

• GH3 β-Glucosidases [1, 2, 3]
• GH16 β-1,3-Glucanase [4]
• GH35 β-1,2-Glucosltransglycosylase [5]
• GH38 α-Mannosidase [6]
• GH57 4-α-Glucanotransferase [7]
• GH94 1,2-β-Oligoglucan phosphorylases [8, 9]
• GH112 D-Galactosyl-β-1,4-L-rhamnose phosphorylase and β-1,3-galactosyl-N-acetylhexosamine phosphorylases [10, 11, 12, 13]
• GH144 Bacterial β-1,2-Glucanases [14, 15]
• GH162 Fungal β-1,2-Glucanase [16]
• GH186 E. coli β-1,2-Glucanase [17]
