Abstract: 5-[(2-nitrobenzyl)oxymethyl]-2’-deoxyuridine 5’-O-triphosphate (dUNBTP) and 5-hydroxymethyl-2’- deoxyuridine 5’-O-triphosphate (dUHMTP) were incorporated to diverse DNA sequences by polymerase synthesis (PEX or PCR). UHM modified DNA was synthesized also through the photolysis of photocaged, UNB-linked DNA. The presence of bulky NB-modification in the recognition sequence of DNA resulted in blocking of cleavage by all restriction endonucleases (REs), however sequences with small HM-modification (formed after irradiation by UV) were perfectly cleaved by all enzymes. Using of photoremovable protecting group in the DNA sequence presents bioorthogonal chemical masking and it has a potential in gene manipulation and cloning.
