Streptococcus pyogenes bacteriocin cluster. (A) Organization of the bacteriocin locus of S. pyogenes, containing four peptides shown by red arrows, Pyogenecin1-4 as Pyo1-4; (B) Multiple sequence alignment of putative bacteriocins using T-Coffee (Notredame et al., 2000), colored using CHROMA software (Goodstadt and Ponting 2001). The GG "double-glycine" leader peptide motif is indicated at (a) and the GxxxG helix-interacting motif at (b).
