Figure 2: Structural comparison of the CPD complexed with Dpo4 and protein free. a, Structures of the CPD (orange) and surrounding nucleic acids in TT-1 (blue), TT-2 (pink) and in the absence of protein (yellow)19 are shown in the ball-and-stick model after superposition of the CPDs. b, c, Ball-and-stick presentations of base-pairing of the CPDs in TT-1 (b) and TT-2 (c). The phosphorus atoms are shown in purple, oxygen in red and nitrogen in dark blue. The carbon atoms of the replicating base pair are white, and others are light blue.
