Research Interests

The current focus of research involves a study of some novel ribosomally-synthesized peptide antibiotics that are produced by gram-positive bacteria. They are subtilin, which is produced by Bacillus subtilis; and nisin, which is produced by Streptococcus lactis. These antibiotic peptides contain many unusual amino acids that are introduced by post-translational modification of a precursor peptide that contains an unusual leader region that directs the secretion of the peptide through a novel secretion pathway
