Method: Solution NMR, 10 models Ligands: BH2, DAL, DBB, LSP, PRD_000195 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function CINA_STRGV Can act as inhibitor of the enzyme phospholipase A2, and of the angiotensin-converting enzyme. Shows inhibitory activities against herpes simplex virus and immunopotentiating activities. Its antimicrobial activities are not very pronounced. Publication Abstract from PubMed The three-dimensional structure of a complex of cinnamycin, a 19-amino acid residue immunopotentiator peptide, and lysophosphatidylethanolamine was determined by 1H-NMR. The complex was cylindrical in shape, 11 A in diameter and 26 A in length, excluding the acyl chain of the phospholipid. The peptide had a hydrophobic pocket surrounded by residues Phe-7 through Ala(S)-14 to bind to the head group of the ligand. Fitting of the head group to the hydrophobic pocket was so good that other than a glycerophosphoethanolamine head group would be unable to fit the pocket. The goodness of the fitting is compatible with the strict specificity of ligand binding of the peptide.
