Respiration-deficient mutants (Rho-, petite) of Saccharomyces carlsbergensis were obtained by treatment with trypaflavin (euflavine). Dried cells of these mutants phosphorylated mononucleotides to their triphosphates and further formed not only cytidine 5'-diphosphate-choline, but also sugar nucleotides, such as uridine 5'-diphosphate-glucose, guanosine 5'-diphosphate-mannose, etc. The activities were the same or slightly greater than those of the wild strain. These results showed that energy (adenosine 5'-triphosphate) necessary for phosphorylation of mononucleotides was sufficiently supplied by the glycolysis system.
