This disclosure relates to conjugates for targeting bacteria and related uses. In certain embodiments, the disclosure relates to methods of transferring a molecule of interest into bacteria comprising mixing bacteria with a non-naturally occurring conjugate under conditions such that the conjugate is transported across the bacterial cell wall. Typically, the conjugate comprises an oligosaccharide and a molecule of interest. In certain embodiments, the molecule of interest may be a tracer or an antibiotic.

A distinguishing feature of the lantibiotic family of cyclic peptides is the presence of thioethers. Treatment of a lantibiotic with an alkaline solution at high pH gives rise to a β-elimination reaction yielding the corresponding ring opened precursor, containing a dehydro-amino acid residue. We here reveal in a proof-of-concept study that a ring opened lantibiotic (mersacidin) can be captured for pull-down from a culture broth, subsequently released and identified by mass spectrometry.

In the last two decades, glyco-gold nanoparticles have emerged as one of several potential new tools for glycoscientists. Glyco-gold nanoparticles consist of the unique structural combination of a goldnanoparticle core and an outer-shell comprising multivalent presentation of carbohydrates. The combination of the distinctive physicochemical properties of the gold core and the biological function/activity
