DNA duplexes containing a monosubstituted pyrophosphate internucleotide group, instead of a phosphodiester bond, were used as cross-linking reagent for the affinity modification of the restriction endonucleases EcoRII and MvaI (R.EcoRII and R.MvaI). An active group was introduced into the enzyme's recognition site or between the recognition site and flanking sequence. The substrate properties of such DNA duplexes were determined. Cross-linking specificity was demonstrated by competition experiments with unmodified substrate, as well as by the absence of cross-linking to an active duplex lacking a recognition site. It was shown that the nucleophilicity of the buffer solution and the presence of the enzyme cofactor Mg2+ dramatically affected the cross-linking yield.

D009838 Oligodeoxyribonucleotides A group of deoxyribonucleotides (up to 12) in which the phosphate residues of each deoxyribonucleotide act as bridges in forming diester linkages between the deoxyribose moieties. Oligodeoxynucleotide,Oligodeoxyribonucleotide,Oligodeoxynucleotides
D011756 Diphosphates Inorganic salts of phosphoric acid that contain two phosphate groups. Diphosphate,Pyrophosphate Analog,Pyrophosphates,Pyrophosphate Analogs,Analog, Pyrophosphate
D003432 Cross-Linking Reagents Reagents with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between side chains of amino acids in proteins; the locations of naturally reactive areas within proteins can thereby be identified; may also be used for other macromolecules, like glycoproteins, nucleic acids, or other.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D015252 Deoxyribonucleases, Type II Site-Specific Enzyme systems containing a single subunit and requiring only magnesium for endonucleolytic activity. The corresponding modification methylases are separate enzymes. The systems recognize specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. EC 3.1.21.4.
