Influence of Amino Acid Substitutions in the Leader Peptide on Maturation and Secretion of Mesentericin Y105 by <i>Leuconostoc mesenteroides</i>

Abstract

By site-specific mutagenesis, the hydrophobic conserved amino acids and the C-terminal GG doublet of the leader peptide of pre-mesentericin Y105 were demonstrated to be critical for optimal secretion of mesentericin Y105, as well as for the maturation of the pre-bacteriocin by the protease portion of the ABC transporter MesD.
