Figure 3From: The Escherichia coli uropathogenic-specific-protein-associated immunity protein 3 (Imu3) has nucleic acid -binding activity Protection of E. coli Usp producing cells by Imu proteins. Colonies encoding: A) usp imu1, imu2 and imu3, B) only usp C) usp imu1, D) usp imu2, and E) usp imu3 gene. The concentrations of the plated transformation mixtures were adjusted to obtain a comparable number of transformants for each strain.Back to article page
