LC-MS ANALYSIS OF NONRIBOSOMAL PEPTIDOME FROM A BRAZILIAN CYANOBACTERIUM NOSTOC SP. CENA543

摘要

Nostoc is a cosmopolitan genus of cyanobacteria found in soils and in symbiotic associations and a prolific producer of bioactive natural products. Nodularin (NOD) is a cyclic nonribosomal pentapeptide, hepatotoxic protein phosphatase inhibitor and tumor promoter. Spumigins are small linear nonribosomal peptide protease inhibitors. Anabaenopeptins are cyclic nonribosomal hexapeptides. Namalides are cyclic tetrapeptides structurally as anabaenopeptin.
