I'd rather not hawk our own work, but here's a structural paper -
Evdokimov, A. G., D. E. Anderson, K. M. Routzahn, and D. S. Waugh. 2001.
Structural basis for oligosaccharide recognition by Pyrococcus furiosus
maltodextrin-binding protein. J. Mol. Biol. 305: 891-904.

and here's some more stuff you might find useful -
Fox, J. D., R. B. Kapust, and D. S. Waugh. 2001. Single amino acid
substitutions on the surface of Escherichia coli maltose-binding protein can
have a profound impact on the solubility of fusion proteins. Protein Sci.
10: 622-630.

Differential effects of short affinity tags on the crystallization of

I can send two of those to you as PDF's - the rest of the data isn't
published :)
