Pyrimidines. A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They include several nucleic acid constituents (CYTOSINE; THYMINE; and URACIL) and form the basic structure of the barbiturates. . 0.73
Deoxyribonuclease (Pyrimidine Dimer). Corrective Endonuclease . Endodeoxyribonuclease (Pyrimidine Dimer) . Endodeoxyribonuclease VIII . Endonuclease V . Endonuclease VIII . Endonuclease, Corrective . An enzyme which catalyzes an endonucleolytic cleavage near PYRIMIDINE DIMERS to produce a 5'-phosphate product. The enzyme acts on the damaged DNA strand, from the 5' side of the damaged site. . 0.70
Pyrimidinones. Pyrimidones . Heterocyclic compounds known as 2-pyrimidones (or 2-hydroxypyrimidines) and 4-pyrimidones (or 4-hydroxypyrimidines) with the general formula C4H4N2O. . 0.64
