Analogues of araNTPs carrying an azido or aminogroup instead of the 2' hydroxyl exhibited substrate properties towards several mammalian and viral DNA polymerases. At the same time, introduction of a bulky hydrophobic DNP group into the 2' position inactivated the compounds as substrates. HSV-1 and CMV DNA polymerases were an interesting exception: they effectively incorporated the modified nucleotide residues with DNP group into the 3'-termini of the DNA chain. This is a reliable distinction of these enzymes from cellular DNA polymerases.

D011685 Purine Nucleotides Purines attached to a RIBOSE and a phosphate that can polymerize to form DNA and RNA. Nucleotides, Purine
D011687 Purines A series of heterocyclic compounds that are variously substituted in nature and are known also as purine bases. They include ADENINE and GUANINE, constituents of nucleic acids, as well as many alkaloids such as CAFFEINE and THEOPHYLLINE. Uric acid is the metabolic end product of purine metabolism.

D003587 Cytomegalovirus A genus of the family HERPESVIRIDAE, subfamily BETAHERPESVIRINAE, infecting the salivary glands, liver, spleen, lungs, eyes, and other organs, in which they produce characteristically enlarged cells with intranuclear inclusions. Infection with Cytomegalovirus is also seen as an opportunistic infection in AIDS.

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).

D004253 DNA Nucleotidylexotransferase A non-template-directed DNA polymerase normally found in vertebrate thymus and bone marrow. It catalyzes the elongation of oligo- or polydeoxynucleotide chains and is widely used as a tool in the differential diagnosis of acute leukemias in man. EC 2.7.7.31.

D004256 DNA Polymerase I A DNA-dependent DNA polymerase characterized in prokaryotes and may be present in higher organisms. It has both 3'-5' and 5'-3' exonuclease activity, but cannot use native double-stranded DNA as template-primer. It is not inhibited by sulfhydryl reagents and is active in both DNA synthesis and repair.
