Abstract
An enzymatic method is described which makes it possible to synthesize labelled pyrimidine deoxyribonucleotides from corresponding labelled ribonucleotides using the RDP‐reductase system of ether‐treated E. coli E125 cells. Ether‐treated cells have been used for the first time for preparative enzymatic synthesis of labelled biologically active compounds.

L-[1.2-13C2, 15N]Serine was prepared from [1,2-13C2, 15N]glycine on a gram scale by the use of the enzyme serine hydroxymethyltransferase. The reaction was monitored by 13C-NMR spectroscopy. This is the first simultaneously 13C- and 15N-labelled serine isotopomer so far reported. Part of the product
