Abstract

Growth of Escherichia coli B in the presence of sub−bacteriostatic concentration of various compounds results in the enhancement of activity of enzymes catalyzing the transformation of uridine to its 5′‐phosphates. Partially purified extracts of E. coli cultivated in the presence of 1×10^−5^M 5‐azacytidine were applied for the preparative synthesis of tritium‐labelled uridine 5′‐triphosphate. Yield of the newly formed nucleotide was about 90% and was higher during the short‐term incubation using enzyme extract from the treated cells than that from controls.
