Solution structure of the antimicrobial peptide [Aba3,5,7,12,14,16]BTD-2
The cyclic cystine ladder in theta-defensins is important for structure and stability, but not antibacterial activity.
Head-to-tail (Arg-Gly) cyclic peptide. Residues 3, 5, 7, 12, 14, and 16 are replaced by alpha-aminobutyric acid.
