Figure 3From: Molecular basis for the distinct divalent cation requirement in the uridylylation of the signal transduction proteins GlnJ and GlnB from Rhodospirillum rubrumTime-course uridylylation of GlnJ, GlnJQ42H, GlnJK85Rand GlnJQ42HK85R. At the time points indicated samples were withdrawn and analyzed by native PAGE. The number of uridylylated subunits (0–3) is indicated.Back to article page
