Cathelicidin LL-37 is a cell signalling compound that stimulates many different cells in humans. One role of cathelicidin LL-37 is stimulating the production of endothelial cells in the formation of capillaries during wound healing. Cathelicidin LL-37 is a protein composed of 37 amino acids. Table 5.1 shows: • the sequence of the first 10 amino acids in the primary structure of cathelicidin LL-37 • DNA triplets in the non-transcribed strand in the gene that codes for the first 10 amino acids in the primary structure of cathelicidin LL-37.
