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 ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

The reoxidation of reducing equivalents, NADH (reduced nicotinamide adenine dinucleotide) and FADH 2 (reduced flavin adenine dinucleotide), that are produced by the oxidation of carbohydrates (the ...
