Placing an 2-nitrobenzyl group on O-6 of the galactosyl residue in uridine-5'-diphosphogalactose (UDP-Gal) gives 6''-O-2-nitrobenzyl-UDP-Gal that is shown to be inactive as a donor substrate for beta-(1-->4)-galactosyltransferase (GalT). On irradiation at 365 nm, the nitrobenzyl group is completely removed yielding native UDP-Gal that then transfers normally to produce the expected betaGal-(1-->4)-betaGlcNAc disaccharidic linkage. 6''-O-2-Nitrobenzyl-UDP-Gal thus fulfils the minimum requirements of a 'caged' UDP-Gal for application in time-resolved crystallographic studies of beta-(1-->4)-GalT.
