Abstract:
Streptococcin A-M49 is produced by certain strains of M-type 49 group A streptococci. The structural gene for streptococcin A-M49 was cloned after hybridization with a probe containing the scnA lantibiotic structural gene. Sequence analysis revealed a duplication of the scnA gene; each gene (scnA' and scnA") encoded a 51-amino-acid prepeptide.
