Nucleotide and corresponding amino acid sequence of the 22.91 kDa protein. The five amino acid sequences found by mass spectrometry are shown under the amino acid sequence (numbered from 1 to 5, starting from the arrows). The amino acids corresponding to the protein sequence are in bold type. Putative signal peptides are underlined and the putative cleavage sites are marked with an ˄. Sequences in red, blue or pink are regions predicted by TMHMM to be located transmembrane (red), intracellular (blue) or extracellular (pink). The active bacteriocin found in the supernatant starts at amino acid position Y101.
