Chronic inflammation involving constant generation of nitric oxide (*NO) by macrophages has been recognized as a factor related to carcinogenesis. At the site of inflammation, nitrosatively deaminated DNA adducts such as 2'-deoxyinosine (dI) and 2'-deoxyxanthosine are primarily formed by *NO
Deoxyinosine (dI) is produced in DNA by the hydrolytic or nitrosative deamination of deoxyadenosine. It is excised in a repair pathway that is initiated by endonuclease V, the product of the nfi gene. The repair was studied in vivo using
The human endonuclease V gene is located in chromosome 17q25.3 and encodes a 282 amino acid protein that shares about 30% sequence identity with bacterial endonuclease V. This study reports biochemical properties of human endonuclease V with respect to repair

To delineate the normal function of purine nucleoside phosphorylase and to understand the pathogenesis of the immune dysfunction associated with deficiency of this enzyme, we studied purine metabolism in a patient deficient in purine nucleoside phosphorylase, her erythrocytes and cultured
Nearest-neighbor thermodynamic parameters of the 'universal pairing base' deoxyinosine were determined for the pairs I.C, I.A, I.T, I.G and I.I adjacent to G.C and A.T pairs. Ultraviolet absorbance melting curves were measured and non-linear regression performed on 84 oligonucleotide duplexes
