Theta-defensins (θ-defensins. retrocyclins) are a family of mammalian antimicrobial peptides. They are found in non-human 'old world' primates, but not in human, gorilla, bonobo, and chimpanzee. == Structure == θ-defensins are cyclic peptides of 18 amino acids (~2 kDa), possessing antimicrobial activity against a range of Gram-positive and Gram-negative bacteria, fungi, and some retroviruses. They consist of a pair of antiparallel β-sheets linked by three disulphide bonds arranged as a ladder along the sheets to form an extremely stable structure. Additionally, the peptides may self-associate into trimers.
