Research Abstract |
We investigated the sugar-binding mechanism of the C-terminal domain of R-type lectin from earthworm (EW29Ch) having a specific sugar-binding activity by nuclear magnetic resonance (NMR) methods. The results showed that the sugar-binding activity of the α binding site in EW29Ch was about 100-fold higher than that of the γ binding site in EW29Ch. Further, the NMR structure analysis and relaxation experiments for EW29Ch suggested that the difference of the sugar-binding activity between the two sugar-binding sites in EW29Ch may be related with the difference of the slow internal motion between those two sugar-binding sites in EW29Ch.
