- The IgA-binding beta antigen of the c protein complex of Group B streptococci: sequence determination of its gene and detection of two binding regionsP G Jerlström
Department of Microbiology, Technical University, Braunschweig, Germany
Mol Microbiol 5:843-9. 1991..Two distinct but adjacent DNA segments specified peptides that bound IgA, which indicates that the IgA-binding activity is located in two distinct regions of the protein...

Department of Microbiology, University of Lund, Sweden
Eur J Immunol 21:1481-90. 1991..This indicates that convergent evolution has favored the appearance of these two structurally different streptococcal IgA receptors...
- Members of the immunoglobulin superfamily in bacteriaA Bateman
MRC Laboratory of Molecular Biology, Cambridge, England
Protein Sci 5:1939-41. 1996..We propose that these prokaryotic immunoglobulin-like domains are almost certain to be related by divergence from a common ancestor to eukaryotic immunoglobulin superfamily domains...
