The incorporation of O6-methyldeoxyguanosine and O4-methyldeoxythymidine monophosphates into DNA by DNA polymerases I and alpha.

Abstract

The modified nucleoside 5'-triphosphates O6-MedGTP ad O4-MedTTP have been synthesised and their acceptability as DNA-precursors investigated using DNA polymerases I and alpha in an in vitro assay. O6-MedGMP is only incorporated into newly-synthesized DNA-like material in the presence of templates containing thymine bases. Similarly O4-MedTMP is only incorporated in the presence of templates containing guanine bases. The results confirm the promutagenic nature and base-pairing properties of O6-MeG ad O4-MeT.
