The simulated modeling of atrazine binding to the QB-site. (A) Stereo view of atrazine binding environment of the L-subunit of Rps. viridis (left) and the D1 protein of S. oleracea (right). (B) Hydrogen bonding interactions for atrazine binding to the QB niche. Here, carbon atoms are shown in grey, nitrogen atoms in blue, oxygen in red, chlorine in green, and hydrogen atoms in white. The possible hydrogen bonds are indicated by dashed lines. (C) Sequence alignment of the Dl protein of C. reinhardtii and S. oleracea with the L-subunit of the Rps. viridis RC. The bacterial L-subunit sequences are in upper case and the Dl sequence is in lower case.
