Figure 5

Amino acid alignment of 22 homB and homA allelic region fragments from segment 2 (720 to 1050 bp; predicted amino acids 240 to 350), showing the six allelic variants. The sequence of the homB product of the J99 strain was used as reference (Genbank accession number NP_223588). The dots refer to sites where the amino acids match those of the reference sequence, the hyphens represent deletions. The boxes are used to separate the 6 different allele groups named AI to AVI. Country of origin is located at the beginning of each strain designation (Pt, Portugal; Sw, Sweden; Gr, Germany; USA; Br, Brazil; Jp, Japan; BF, Burkina Faso). * Allelic variants exclusive of homB; allelic variant exclusive of homA.
