Coordination chemistry and antimicrobial activity of LL-37, its C-terminal fragment, and a peptidomimetic analogue.
Human cathelicidin LL-37 is an antimicrobial peptide naturally present in saliva that plays an important role in host defence against bacterial and fungal pathogens. Although LL-37 is known to bind Cu(II) and Zn(II) ions, the corresponding coordination modes have remained unresolved. Here, the metal-binding properties,...
