as the neomycin phosphotransferase phosphorylates the specific hydroxyl group of the sugar in the aminoglycosides , such as 3'oh of the glucose residue of kanamycin a , some specific sugar ( s ) on the molecules exposed on the cell surface must be responsible for the suppressive signal and their phosphorylation must have resulted in the loss of that signal .
