Catalysis of the hydrolytic removal of phosphoglycolate from the 3'-terminus of a 3'-phosphoglycolate-terminated DNA strand. [GOC:pde, GOC:rb, PMID:11238902]
Phosphodiesterase activity, acting on 3'-phosphoglycolate-terminated DNA strands, involves the enzymatic hydrolysis of the phosphodiester bond located at the 3'-end of a DNA strand that has been terminated with a 3'-phosphoglycolate group. This specific type of phosphodiesterase is involved in DNA repair pathways, specifically in the removal of 3'-phosphoglycolate lesions that can arise from oxidative damage to DNA. 3'-phosphoglycolate residues are generated by the action of reactive oxygen species (ROS) on DNA, leading to the formation of a covalent bond between the 3'-hydroxyl group of deoxyribose and a glycolate moiety. These lesions can block DNA replication and transcription, potentially leading to cell death or mutations. The 3'-phosphoglycolate-specific phosphodiesterase removes the 3'-phosphoglycolate group, restoring the integrity of the DNA strand and enabling the resumption of normal DNA processes.'

| DNA-(apurinic or apyrimidinic site) endonuclease | A DNA-(apurinic or apyrimidinic site) endonuclease that is encoded in the genome of human. [PRO:DNx, UniProtKB:P27695] | Homo sapiens (human) |
| Compound | Definition | Classes | Roles |
|---|---|---|---|
| aurintricarboxylic acid | aurintricarboxylic acid : A member of the class of quinomethanes that is 3-methylidene-6-oxocyclohexa-1,4-diene-1-carboxylic acid in which the methylidene hydrogens are replaced by 4-carboxy-3-hydroxyphenyl groups. The trisodium salt is the biological stain 'chrome violet CG' while the triammonium salt is 'aluminon'. Aurintricarboxylic Acid: A dye which inhibits protein biosynthesis at the initial stages. The ammonium salt (aluminon) is a reagent for the colorimetric estimation of aluminum in water, foods, and tissues. | monohydroxybenzoic acid; quinomethanes; tricarboxylic acid | fluorochrome; histological dye; insulin-like growth factor receptor 1 antagonist |
| hycanthone | hycanthone : A thioxanthen-9-one compound having a hydroxymethyl substituent at the 1-position and a 2-[(diethylamino)ethyl]amino substituent at the 4-position. It was formerly used (particularly as the monomethanesulfonic acid salt) as a schistosomicide for individual or mass treatement of infection with Schistosoma haematobium and S. mansoni, but due to its toxicity and concern about possible carcinogenicity, it has been replaced by other drugs such as praziquantel. Hycanthone: Potentially toxic, but effective antischistosomal agent, it is a metabolite of LUCANTHONE. | thioxanthenes | mutagen; schistosomicide drug |
| lucanthone | lucanthone : A thioxanthen-9-one compound having a methyl substituent at the 1-position and a 2-[(diethylamino)ethyl]amino substituent at the 4-position. Formerly used for the treatment of schistosomiasis. It is a prodrug, being metabolised to hycanthone. Lucanthone: One of the SCHISTOSOMICIDES, it has been replaced largely by HYCANTHONE and more recently PRAZIQUANTEL.
