Summation

Dermcidin peptides, DCD1(63-109) and DCD-1L(63-110), are anionic peptides with a net negative charge of -2 at physiological pH (Paulmann M et al. 2012). Despite its negative net charge, DCD peptides possess an amphiphilic structure due to its cationic N-terminal region (Ser1 to Lys23) and its anionic C-terminal part (Asp24 to Leu48). The cationic N-terminal part is mainly responsible for the binding of DCD to the negatively charged phospholipids.
