Biological & pharmaceutical bulletin, 22(4), 333-338 (1999-05-18)

We developed a novel fluorometric assay method for the measurement of glycosyltransferase activities using mono- and di-saccharides aminated and tagged with 7-hydroxycoumarin-3-carboxylic acid (coumarin) as substrates, N-acetylglucosamine (GlcNAc)-coumarin for beta1,4-galactosyltransferase from bovine milk and Gal beta1-4GlcNAc-coumarin for alpha2,3- and alpha2,6-sialyltransferases

Protein labeling provides significant information about protein function. In this research, we developed a novel protein labeling technique by utilizing photoactive yellow protein (PYP). PYP is a small protein (14 kDa) derived from purple bacteria and binds to 7-hydroxycoumarin-3-carboxylic acid
