MeSH note : found in MutT protein of E coli & in humans; hydrolyzes 8-oxodGTP to 8-oxodGMP; also
degrades dGTP & dATP to dGMP & dAMP, respectively; MW 18 kDa; prevents A.T to C.G
transversion caused by 8-oxodGTP, which forms spontaneously in nucleotide pool of
E coli; mutant form with Met replacing Val at position 83 may be antimutagenic for
human cancer;
