Literature

Crystal structure of the C2 fragment of streptococcal protein G in complex with the Fc domain of human IgG.

  • PubMed Abstract: 

    Streptococcal protein G comprises two or three domains that bind to the constant Fc region of most mammalian immunoglobulin Gs (IgGs). Protein G is functionally related to staphylococcal protein A, with which it shares neither sequence nor structural homology.
