Popis: A homogeneous peptide with a mass of 683 Da which inhibits HIV-1 integrase with IC50 3 × 10−5 M was separated from aqueous extracts of a marine worm Eunicidae sp. by multistage chromatography purification. The Asp-Leu-Hse-His-Ala-Gln structure was proposed for this peptide according to amino acid analysis, automated amino acid Edman sequences, and TLC with witness homoserine and MS/MS fragmentation. The proposed structure is the first example of a natural peptide containing an amino acid homoserine residue.
