Aminoglycoside antibiotics: Synthesis of 5"-amino-5"-deoxyneomycin and 5"-amino-5"-deoxyparomomycin.
DNA methylation (5-methylcytosine, 5mC) plays critical biological functions in mammals and plants as a vital epigenetic marker. The Ten-Eleven translocation dioxygenases (TET1, 2, and 3) have been found to oxidize 5mC to 5-hydroxymethylcytosine (5hmC) and then to 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) in mammalian cells. We report herein three mushroom TET homologues from Coprinop...
Emerging data strongly suggest that the oxidation of DNA bases can contribute to genomic instability. Structural changes to DNA, induced by base oxidation, may reduce the fidelity of DNA replication and interfere with sequence-specific DNA-protein interactions. We have examined the structures of a series of pyrimidine deoxynucleoside oxidation damage products in aqueous solution. The modified n...
Individual DNA molecules can be read at single nucleotide precision using nanopores coupled to processive enzymes. Discrimination among the four canonical bases has been achieved, as has discrimination among cytosine, 5-methylcytosine (mC), and 5-hydroxymethylcytosine (hmC). Two additional modified cytosine bases, 5-carboxylcytosine (caC) and 5-formylcytosine (fC), are produced during enzymatic...
