DNA-peptide (DpCs) and DNA-protein cross-links (DPCs) are DNA lesions formed when the ploypeptides or cellular proteins get covalently trapped onto the genomic DNA. DNA-protein cross-links are of enormous size and hence pose challenges to the DNA repair machineries thereby blocking the DNA replication. However, DPCs can undergo proteolytic degradation via various pathways to give shorter polypeptide chains (DpCs). These DpC lesions are efficiently bypassed by TLS polymerases like κ, η, δ, etc, although the bypass efficiency as well as correct base insertion depends heavily on size, sequence context, and position of peptides in DpCs. This chapter explores various synthetic methods to synthesize these lesions and presents detailed procedures for the construction of DpCs and DPCs both via reductive amination as well as oxime ligation. Further we described biochemical experiments to investigate the effects of these lesions on DNA polymerase activity and fidelity.
