Alignment of fhbp carrying single nucleotide insertions/deletions. Alignment of fHBP nucleotide sequences in the region surrounding a single nucleotide deletion in B110 and B139 at nucleotide 365 (arrow, position b). B138 and B140 carry the same deletion but each has a compensating insertion of a T after nucleotide 340 (a) or 385 (c), respectively, that restores the correct reading frame within 7–9 amino acids.
