== Publication Abstract from PubMed ==
</table>
Bridge not required: The disulfide bridge in the antibacterial peptide leucocin A was replaced with two Ser or two Leu residues. The double leucine mutant was found to be active, and elucidation of its 3D structure showed that the two leucines interact to hold the N- and C-terminal domains together.
== Function ==
 
[https://www.uniprot.org/uniprot/LCCA_LEUGE LCCA_LEUGE] Inhibits a wide spectrum of lactic acid bacteria.
