Figure 5. Hydrogen bonding interactions important for atrazine binding to the RC. (a) Carbon atoms are shown in black, nitrogen atoms in blue, oxygen in red, chlorine in green, and hydrogen atoms in white. (b) Comparison to the distal (green, 1PRC[new]) and proximal (black, 2PRC) ubiquinone binding sites [Lancaster and Michel 1997]. The structure of the atrazine complex (5PRC) is shown in pink.
