title: Syntheses and properties of photoactivatable sugar derivatives designed to probe the sugar-binding site of melibiose permease.
abstract: Three new photoreactive sugar analogues bearing an azido, a diazonium salt or a diazirine group as the photophore as well as a tritium atom were developed. Two of these new photoactivatable compounds gave excellent preliminary results, with a high affinity for the melibiose permease of Escherichia coli.
