WebThe biosynthesis of AHBA has been studied in organisms producing various ansamycins and mitomycin C through the incorporation of 13C- and 14C-enriched glucose, glycerate, and other precursors. This work led to the hypothesis that the seven-carbon mC 7 N unit is derived from the shikimate biosyn-thesis pathway (20–23). Genetic investigations ... WebAnsamycins are lipophilic macrocyclic antibiotics that easily diffuse through membranes. They comprise two aromatic rings (containing a quinone), connected by a long chain (or ‘ansa’– hence the name given to this class of antibiotics), which confers a rigid character to the whole molecule. The first clinically developed and major ...
