Identification of nucleotide sequence involved in Weissellicin L production.

ABSTRACT:

Background

Weissellicin L, a novel bacteriocin produced by Weissella hellenica 4-7, was previously characterized but its full amino acid sequence remain unknown. The draft genome sequencing analysis of Weissella hellenica 4-7 was performed and the open reading frame (ORF) encoding the weissellicin L was identified and clarified.

Findings

The obtained results indicated that the mature bacteriocin consists of 29 amino acid residues with a molecular weight of approximately 3205.64 Da. A conserved processing site of two glycine residues in positions -1 and -2 was observed in the leader peptides. The possibility that bacteriocin secretion depended on ATP-binding cassette (ABC) transporter was therefore suggested. Furthermore, primers were designed from 5' and 3' flanking sequence
