При этом донором фосфатной группы служил ацетилфосфат. В качестве биокатализаторов применяли цитидиндезаминазу, уридинфосфорилазу, пуриннуклеозидфосфорилазу и дезоксинуклеозидкиназу, выделенные из клеток ранее сконструированных штаммов Escherichia coli.

Acetylphosphate was used as a donor of phosphate group. Cytidine deaminase, uridine phosphorylase, purine nucleoside phosphorylase and deoxynucleoside kinase recovered from earlier designed strains of Escherichia coli were used as biocatalysts.
