Takayuki Ohnuma is an assistant professor at Department of Advanced Bioscience, Faculty of Agriculture, Kinki University located in Nara, Japan.
He received PhD degree in 2002 from Graduate School of Agriculture in Kyushu University. His research program currently focuses on the structures and functions of plant chitinases (GH18 and GH19), including their CBMs (CBM18 and CBM50), which are involved in plant self-defense against fungal pathogens. In 2013, He and his colabolater published [9] the structure of a complex of rye family 19 chitinase with two molecules of (GlcNAc)4. This is the first report on the complete subsite mapping of GH19 chitinase.
