Nucleoside Glycosyl Dihydrogen Pyrophosphates

When wet cells of Aerobacter aerogenes were extracted with boiling 70 % ethanol and the extract chromatographed, the uridine 5-(glycosyl dihy- 

In yeasts, the catalytic amounts of uridine 5-(D-glucosyl dihydrogen pyrophosphate) necessary could also be formed by the action of UDP-glucose pyrophosphorylase, which catalyzes the reaction  

The penicillin-inhibited incorporation of uracil-C into nucleic acids resulted in a corresponding accumulation in the nucleotides. The separation 

The compounds which accumulate in novobiocin-treated cells are identical with those for the penicillin-treated cells. 

The sequence and the configuration of the amino acids have recently been determined in the following accumulated compounds.
