Design Notes
LL-37 is the only cathelicidin-derived antimicrobial peptide found in humans (Dürr, Sudheendra and Ramamoorthy, 2006). Mature LL-37 has 37 amino acid residues starting with two leucines (NH2-LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES-COOH).The peptide is cleaved from a larger protein, hCAP-18, by extracellular proteolysis of proteinase 3 from the C-terminal end of hCAP18(Patricia, 2010; Ramos, Domingues, and Gama, 2011).The peptide is composed of two main parts: from residues Leu2 to Leu31, which is a α-helical structure(Fig 2b), and a 6 residues form the loop structure at the terminus. Ramos, Domingues, and Gama (2011) also reported that LL-37 has additional roles such as regulating the inflammatory response in wounds or infection sites, binding and neutralizing lipopolysaccharide (LPS), and wound closure, apart from its anti-microbial property.
