Diagram of the DNA structure containing N3-meC:G. (A) Structure of dsDNA2 with N3-meC:G. N3-meC5 in magenta, opposite G10’ in blue. dsDNA 2: 5′-CTGT(3meC)TC*ATTGCG-3′ paired with 5′-TCGCAATAAGACA-3′. (B) Structure of dsDNA2 with N3-meC:G aligned with the unlesioned dsDNA in structure 3BTX. DNA- containing N3-meC in red, unlesioned DNA in green. dsDNA in 3BTX: 5′-CTGTATC*ATT GCG-3′ paired with 5′-TCGCAATAATACA-3′. Different packing pattern at the end of the dsDNA is observed.
