Salivaricin G32, a Homolog of the Prototype Streptococcus pyogenes Nisin-Like Lantibiotic SA-FF22, Produced by the Commensal Species Streptococcus salivarius
Figure 2
(1) Alignment of (a) the leader sequences and (b) the propeptide sequences of salivaricin G32, SA-FF22, and macedocin (- indicates a spacer introduced to aid the alignment). The N-terminal sequence derived from the purified G32 preparation is shown below, where X indicates a blank cycle in the Edman reaction. (2) Alignment of (a) the predicted translated leader sequences and (b) the predicted translated propeptide sequences for slnA1, scnA1, and mcdA1. The number of amino acids in each sequence is indicated in front of each sequence name.
