Some glycosylase-lyases can further perform δ-elimination, which converts the 3' aldehyde to a 3' phosphate. A wide variety of glycosylases have evolved to recognize different damaged bases. Examples of DNA glycosylases include Ogg1, which recognizes 8-oxoguanine, MPG, which recognizes 3-methyladenine, and UNG, which removes uracil from DNA.
UNG is known to be the major player in uracil removal but when depleted SMUG1 can provide a backup for UNG in the antibody diversification process. [11] [12] In addition to uracil, SMUG1 removes several pyrimidine oxidation products. [13] and has a specific function to remove the thymine oxidation product 5-hydroxymethyl uracil from DNA. [14]
Uracil-DNA glycosylases are DNA repair enzymes that excise uracil residues from DNA by cleaving the N-glycosydic bond, initiating the base excision repair pathway. Uracil in DNA can arise either through the deamination of cytosine to form mutagenic U:G mispairs, or through the incorporation of dUMP by DNA polymerase to form U:A pairs . [ 18 ]
Double-stranded uracil-DNA glycosylase (EC 3.2.2.28, Mug, double-strand uracil-DNA glycosylase, Dug, dsUDG, double-stranded DNA specific UDG, dsDNA specific UDG, UdgB, G:T/U mismatch-specific DNA glycosylase, UDG) is an enzyme with systematic name uracil-double-stranded DNA deoxyribohydrolase (uracil-releasing). [1] [2] [3] This enzyme ...

DNA glycosylases first create abasic sites by recognizing and removing modified bases. Many glycosylase variants exist to deal with the multiple ways a base can be damaged. The most common circumstances are base alkylation, oxidation, and the presence of a uracil in the DNA strand. [4]
