such as oxidation, reduction, and methylation. One of the most important properties of guanine is its ability to form three hydrogen bonds with cytosine. This strong base pairing is crucial for the ...

The DNA glycosylase MutY, which is a member of the Helix-hairpin-Helix (HhH) DNA glycosylase superfamily, excises adenine from mispairs with 8-oxoguanine and guanine. High-resolution crystal ...

Adenine can exist in different tautomeric forms, with the amino group (-NH 2) at position 6 being the most stable. This tautomerism is crucial for the correct base pairing with thymine or uracil, as ...
