Derewenda, Z, Yariv, J, Helliwell, J R, Kalb, A J, Dodson, E J, Papiz, M Z, ...

A complex of concanavalin A with methyl alpha-D-mannopyranoside has been crystallized in space group P212121 with a = 123.9 A, b = 129.1 A and c = 67.5 A. X-ray diffraction intensities to 2.9 A...

The 15-K neutron structure of saccharide-free concanavalin A

Blakeley, M. P., Kalb (Gilboa), A. J., Helliwell, J. R., Myles, D. A. A.

The positions of the ordered hydrogen isotopes of a protein and its bound solvent can be determined by using neutron crystallography. Furthermore, by collecting neutron data at cryo temperatures, the...
