Abstract
A method of assaying, detecting, monitoring, and influencing in vitro and in vivo activity of glycosyltransferase and sugar nucleotides which are analogs of the naturally-occurring sugar nucleotides for which the glycosyltransferases are specific. These sugar nucleotide analogs include those labeled with a fluorogenic moiety at the 2' or 3' position of the ribose or at another location (e.g., on a constituent phosphate or in the nucleotide backbone), such as the UDP-galactose analog, 2'(or 3')-O-(2,4,6-trinitrophenyl)-5'-uridine diphosphate galactose (TUG). A highly specific assay for soluble glycosyltransferase has been developed which utilizes the fluorogenic sugar-nucleotide analogs. These assays rely on changes in spectral properties resulting from specific binding events of the sugar nucleotide analog and the glycosyltransferase. Assays of this invention do not rely on the use of radio-isotopes and can be used to assess glycosyltransferase activity in living cells.
