| + | DNA photoproducts with (6-4) pyrimidine-pyrimidone adducts formed by ultraviolet radiation have been implicated in mutagenesis and cancer. The crystal structure of double-stranded DNA containing the (6-4) photoproduct in complex with the anti-(6-4)-photoproduct antibody 64M-5 Fab was determined at 2.5 A resolution. The T(6-4)T segment and the 5'-side adjacent adenosine are flipped out of the duplex and are accommodated in the concave antigen-binding pocket composed of six complementarity-determining regions (CDRs). A loop comprised of CDR L1 residues is inserted between the flipped-out T(6-4)T segment and the complementary DNA. The separation of strands by the insertion of the loop facilitates extensive and specific recognition of the photoproduct. The DNA helices flanking the T(6-4)T segment are kinked by 87 degrees . The 64M-5 Fab recognizes the T(6-4)T segment dissociated from the complementary strand, indicating that the (6-4) photoproduct can be detected in double-stranded DNA as well as in single-stranded DNA using the 64M-5 antibody. The structure and recognition mode of the 64M-5 antibody were compared with those of the DNA (6-4) photolyase and nucleotide-excision repair protein DDB1-DDB2. These proteins have distinctive binding-site structures that are appropriate for their functions, and the flipping out of the photolesion and the kinking of the DNA are common to mutagenic (6-4) photoproducts recognized by proteins. | ||
