Additional NMR Experimental Information
DetailsTRIOSTIN A CONTAINS TWO PLANAR AROMATIC QUINOXALINE RINGS THAT ARE COVALENTLY ATTACHED TO A CYCLIC OCTADEPSIPEPTIDE RING REPRESENTED BY CHAINS A AND B IN THIS ENTRY. THERE IS A DISULFIDE BRIDGE LINKING CYS A 4 TO CYS B 9. BOTH CYS AND VAL RESIDUES CONTAIN METHYLATED AMIDE NITROGENS; THE TWO D-SER RESIDUES ARE AMIDE BONDED TO THE TWO QUINOXALINE RINGS.
