Protein G

Protein G, streptococcal is a cell surface-associated protein from streptococcus that binds to IgG with high affinity. It has three highly homologous IgG-binding domains.

The NMR solution structure (Lian, et.al. 1992. Journal of Mol. Biol. 228:1219-1234) and the crystal structure (Derrick and Wigley. 1994. Journal of Mol. Biol. 243:906-918) has been resolved at 1 angstrom. Extensive studies of both the solution structure and the crystal structure using NMR and X-ray crystallography has made Protein G a model for the development of novel NMR methods.
