The complete amino acid sequence of protein B (= CAMP factor) of Streptococcus agalactiae has been determined. The sequence data were obtained mainly by manual sequencing of peptides derived from digestion with lysyl‐peptidase, clostripain ans Staphylococcus aureus protease and by solid phase sequencing of cyanogen bromide fragments. The protein contains 226 amino acids and has an M r of 25 263. The sequence was compared with sequences of other Fc‐binding proteins and partial sequence homology was found between protein B and the Fc‐binding region of protein A.
