Guanosine diphosphate glucose and guanosine diphosphate fructose from Eremothecium ashbyii

Abstract

Guanosine diphosphate mannose and 2 hitherto unidentified nucleotides have been isolated from the mold E. ashbyii by ion-exchange and paper chromatography. Although the new nucleotides were not separated from guanosine diphosphate mannose they were shown to be guanosine diphosphate glucose and guanosine diphosphate fructose. In guanosine diphosphate glucose a guanosine 5[image]-pyrophosphate residue is joined through its terminal phosphate, probably to position 1 of glucose. The position of the linkage between fructose and the pyrophosphate in guanosine diphosphate fructose is not settled.
