The nucleotide sequence of the gene encoding the K88ac fimbrial subunit has been determined and the amino acid sequence was derived. In comparison with the two other, previously determined sequences of the K88ab and K88ad sequences, the most striking features of the K88ac protein sequence are the insertion of a lys residue at position 104 and the deletion of three amino residues at positions 165. The differences between the three sequences are discussed with respect to possible structure‐functions relationships and antigenic determinants.
