title: In vitro and in vivo reactions of nucleic acids with reducing sugars.
abstract: Reducing sugars such as glucose and glucose 6-phosphate have been shown to nonenzymatically react with the amino groups of proteins. The modification of proteins by reducing sugars can alter both physical characteristics and biological functions. Analogous to the reaction observed with proteins, the amino groups of DNA bases are also able to react nonenzymatically with reducing sugars. The modifications of DNA by reducing sugars result in the time- and sugar-concentration-dependent changes in biological properties. In this communication we review data describing in vitro and in vivo models we have used to investigate the biological consequences of the nonenzymatic glycosylation of DNA.
