Lactobacillus amylovorus DCE 471 produces amylovorin L, a bacteriocin with an antibacterial activity against some strains of the Lactobacillus lineage. Based on the sequence of one active peptide, a gene encoding active amylovorin L was cloned and sequenced. Genome walking allowed us to sequence a larger fragment of 7577 bp of genomic DNA, with 12 predicted ORFs. The previously characterized amylovorin L peptide-encoding gene is preceded by another gene encoding a small polypeptide with a typical bacteriocin-processing double-glycine site, suggesting that amylovorin L is a two-component cla…
