Abstract

Crude cell‐free extracts of Escherichia coli AB 259 Hfr 3000, thi‐perform multistep conversion of ^14^C‐uracil to ^14^C‐UTP in vitro in the presence of D‐ribose/or ribose‐5‐phosphate/, ATP and ATP‐regenerating system. ATP concentration is crucial for significant ^14^C‐UTP production. Quantitative yield of the product combined with relatively simple procedure and inexpensiveness of initial materials makes the method advantageous for large‐scale preparation of ^14^C‐UTP.
