Human alpha 4 defensins is synthesized from 97 precursor (mature peptide 64-96). A 17-aa peptide sequence near the C-terminus of human mature alpha defensin-4. Defensins are a large family of broad-spectrum antimicrobial peptides, identified originally in leukocytes of rabbits and humans. Defensins, cationic/polar...

Defensins are a large family of broad-spectrum antimicrobial peptides, identified originally in leukocytes of rabbits and humans. Defensins, cationic/polar peptides (30-35 aa, 3-4kD), are distinguished by a conserved tri-disulfides and a largely b-sheet structure. Defensins, expressed at the cell surface, have been...
