Peptide derivatives of tachyplesin having antimicrobial activity

摘要

Compositions comprising antimicrobial peptides are provided. The peptides are derivatives of tachyplesin having amino acid substitutions in which the four cysteine residues are replaced with hydrophobic amino acids. The compositions are useful in methods of the control of fungal and bacterial activity in agricultural and medical applications. Methods for making and using the compounds of the invention are additionally provided.
