RESUMO
Avermectins and ivermectins are glycosylated at C-4'' and C-4' by both growing and resting cells of Saccharopolyspora erythraea. The reaction is catalyzed by a glycosyltransferase which is constitutive. The enzyme uses UDP-glucose as the glycosyl donor and avermectin or ivermectin mono- and disaccharides as acceptors. Avermectin and ivermectin aglycones and erythromycin A are not substrates for the enzyme.
