| + | Based on genome mining, a new lasso peptide specialicin was isolated from the extract of Streptomyces specialis. The structure of specialicin was established by ESI-MS and NMR analyses to be a lasso peptide with the length of 21 amino acids, containing an isopeptide bond and two disulfide bonds in the molecule. The stereochemistries of the constituent amino acids except for Trp were determined to be L and the stereochemistry of Trp at C-terminus was determined to be D. Three dimensional structure of specialicin was determined based on NOE experimental data, which indicated that specialicin possessed the similar conformational structure with siamycin I. Specialicin showed the antibacterial activity against Micrococcus luteus and the moderate anti-HIV activity against HIV-1 NL4-3. The biosynthetic gene cluster of specialicin was proposed from the genome sequence data of S. specialis. | ||
