In molecular biology the GA module or protein G-related albumin-binding module is a protein domain which occurs on the surface of numerous Gram-positive bacterial pathogens. Protein G of group C and G Streptococci interacts with the constant region of IgG and with human serum albumin. The GA module is composed of a left-handed three-helix bundle and is found in a range of bacterial cell surface proteins.
