Proline Effect on Structure and Activity of Antimicrobial Peptides

초록

Structure and activity of a helical antimicrobial peptide with a central proline (P14) and its alanine derivative (P14A) were investigated by NMR spectroscopy and biological assay. Chemical shift analysis showed that both of the peptides formed curved helix and P14 showed diminished stability near proline due to hindrance of hydrogen bonding by proline.(omitted)
