The biosynthesis of avilamycin, an oligosaccharide antibiotic, starts with the formation of a disaccharide synthesised from d-glucose. AviX12 is involved in C-2 epimerization of the glucose moiety after the whole avilamycin molecule has been formed to form the d-mannose stereoisomer. Unusually, the C-2 carbon is an uncativated centre, and it is thought that AviX12 generates the 5'deoxyadenosyl radical, which abstracts a hydrogen atom a position C-2 of the mannose moiety to form a radical intermediate. This intermediate undergoes epimerization by an unknown mechanism.
