Function

[8ODP_HUMAN] Antimutagenic. Acts as a sanitizing enzyme for oxidized nucleotide pools, thus suppressing cell dysfunction and death induced by oxidative stress. Hydrolyzes 8-oxo-dGTP, 8-oxo-dATP and 2-OH-dATP, thus preventing misincorporation of oxidized purine nucleoside triphosphates into DNA and subsequently preventing A:T to C:G and G:C to T:A transversions. Able to hydrolyze also the corresponding ribonucleotides, 2-OH-ATP, 8-oxo-GTP and 8-oxo-ATP.^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

The probe-based discovery of the first small-molecule inhibitor of the repair enzyme 8-oxo-dGTPase (MTH1) is presented, which is an unconventional cyclometalated ruthenium half-sandwich complex. The organometallic inhibitor with low-nanomolar activity displays astonishing specificity, as verified in tests with an extended panel of protein kinases and other ATP binding proteins. The binding of the organometallic inhibitor to MTH1 is investigated by protein crystallography.

An organometallic inhibitor for the human repair enzyme 7,8-dihydro-8-oxoguanosine triphosphatase.,Streib M, Kraling K, Richter K, Xie X, Steuber H, Meggers E Angew Chem Int Ed Engl. 2014 Jan 3;53(1):305-9. doi: 10.1002/anie.201307849. Epub, 2013 Nov 20. PMID:24258965^[6]
