Fig. 1From: The fungal gene cluster for biosynthesis of the antibacterial agent viriditoxinStructures of (M)-viriditoxin and (P)-viriditoxin (1 and 1′), as well as related metabolites produced by other fungi. The “M” and “P” refer to the atropisomer confirmations, with the helical configurations illustrated by the bold lines. 1 is the major form produced by A. viridinutans and P. variotii. Carbon numbers C3, C4 and C7 are indicatedBack to article page
