Antimicrobial peptides from animals, plants and fungi organised by their secondary structure content. Circle size indicates overall molecular weight of each peptide. Antimicrobial peptides are a unique and diverse group of molecules, which are divided into subgroups on the basis of their amino acid composition and structure. [3]

Cathelicidin antimicrobial peptide (CAMP) is an antimicrobial peptide encoded in the human by the CAMP gene. [1] The active form is LL-37.In humans, CAMP encodes the peptide precursor CAP-18 (18 kDa), which is processed by proteinase 3-mediated extracellular cleavage into the active form LL-37.
This indicates potential for therapeutic application of antimicrobial peptides in cancer, where treatment with cecropins could lower the required dosage of chemotherapy drugs, reducing undesirable side effects. Major challenges to the use of cecropins as cancer therapeutics are delivery of the peptides to tumor cells.
There are numerous types of peptides that have been classified according to their sources and functions. According to the Handbook of Biologically Active Peptides, some groups of peptides include plant peptides, bacterial/antibiotic peptides, fungal peptides, invertebrate peptides, amphibian/skin peptides, venom peptides, cancer/anticancer peptides, vaccine peptides, immune/inflammatory ...
A number of these defence peptides are secreted from the skin of frogs and other amphibians, including the opiate-like dermorphins and deltorphins, and antimicrobial dermaseptins, temporins, bombinins, magainin, pseudin, bombesins, and maculatins. [1] [2]
Dermcidin is a protein with 110 amino acids that in humans is encoded by the DCD gene. [3] [4] The full-length protein produces derived peptides as proteolysis-inducing factor (PIF) and other anti-microbial peptides, [4] secreted by human eccrine sweat glands onto the skin as a part of the innate host defense of the immune system.
The magainins are a class of antimicrobial peptides found in the African clawed frog (Xenopus laevis). [1] The peptides are cationic, generally lack a stable conformation in water but form amphipathic α-helix in membranes; their mechanism against micro-organisms is unclear but they disrupt the cell membranes of a broad spectrum of bacteria, protozoa, and fungi.
