Structural plasticity of peanut lectin: an X-ray analysis involving variation in pH, ligand binding and crystal structure

S. Kundhavai Natchiar, A. Arockia Jeyaprakash, T. N. C. Ramya, C. J. Thomas, K. Suguna, A. Surolia and M. Vijayan

Synopsis: The rigid and the flexible regions of the peanut lectin molecule have been delineated and the invariant water molecules in its hydration shell identified using the structures of the lectin crystals containing ligand-bound and ligand-free subunits, grown under different environmental conditions. The molecule is sturdy and the combining site is essentially preformed.

Refinement of Haemophilus influenzae diaminopimelic acid epimerase (DapF) at 1.75 Å resolution suggests a mechanism for stereocontrol during catalysis

A. J. Lloyd, T. Huyton, J. Turkenburg and D. I. Roper

Synopsis: The crystal structure of diaminopimelate epimerase has been refined to 1.75 Å, highlighting differences from the previously determined structure and enabling mechanistic deductions and comparisons with the functionally related amino-acid racemases to be made.

Structure of the saccharide-binding domain of the human natural killer cell inhibitory receptor p75/AIRM1

N. Dimasi, A. Moretta, L. Moretta, R. Biassoni and R. A. Mariuzza

Synopsis: p75/AIRM1, also known as Siglec-7, is a sialoadhesin expressed on natural killer cells that is able to inhibit their cytolytic activity. The X-ray crystal structure of the extracellular IgV-like domain, thought to be involved in target-cell recognition, has been determined at higher resolution (1.45 Å) and in a different space group to the previously reported Siglec-7 structure.
