abstract = {Human LL-37$_{17–29}$ is an antimicrobial peptide forming
thermostable supramolecular fibrils that surround bacterial
cells. The crystal structure of LL-37$_{17–29}$ bearing an
I24C substitution of most buried position in the fibril
revealed disulfide-bonded dimers that further assembled into
a fibrillar structure of densely packed helices. We further
demonstrated the position-dependent controllable
antibacterial activity of LL-37$_{17–29}$ I24C and other
cysteine mutants, mediated by regulation of intermolecular
disulfide bonds and their role in the formation of
supramolecular structures. The morphology of the fibrils and
their antibacterial mechanism of action might be dependent
on their interactions with specific bacteria. The
significant effect of disulfide bonds on the assembly into
supramolecular structures and their sensitivity to
reducing/oxidizing conditions may explain why short helical
antimicrobial peptides with a single cysteine and an odd
number of cysteines are selected against in nature.},
