Figure 1

Alignment of inferred N-terminal amino acid sequences of 33 alleles of emm1. The region shown represents amino acids 27 through 110 (GenBank accession number X07860). Six of the emm1 alleles were identified in this study, several were described previously (1,5,12), and others were from ongoing analysis of emm1 in M1 strains from global sources. Amino acid residues identical to those encoded by emm1.0 are represented by periods.
