The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Hypothetical protein; domain 2
".
FunFam 4: DNA-3-methyladenine glycosylase II
Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.
There are 8 GO terms relating to "molecular function"

Alkylbase DNA N-glycosylase activity GO:0003905
Catalysis of the reaction: DNA with alkylated base + H2O = DNA with abasic site + alkylated base. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the target damaged DNA base and the deoxyribose sugar to remove an alkylated base, leaving an apyrimidinic or apurinic site.

DNA-3-methyladenine glycosylase activity GO:0008725
Catalysis of the reaction: DNA containing 3-methyladenine + H2O = DNA with abasic site + 3-methyladenine. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the damaged DNA 3-methyladenine and the deoxyribose sugar to remove the 3-methyladenine, leaving an abasic site.

Base-excision repair, AP site formation GO:0006285
The formation of an AP site, a deoxyribose sugar with a missing base, by DNA glycosylase which recognizes an altered base in DNA and catalyzes its hydrolytic removal. This sugar phosphate is the substrate recognized by the AP endonuclease, which cuts the DNA phosphodiester backbone at the 5' side of the altered site to leave a gap which is subsequently repaired.

DNA dealkylation involved in DNA repair GO:0006307

Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
