Single crystals of 2-thiouracil were irradiated and studied at 77 K by electron-spin resonance spectroscopy. The dominant radical trapped exhibits a resonance pattern consisting of a doublet of ...

THREE pyrimidines have been found to occur in Nature as constituents of the nucleoproteins, the chief protein material of the cell nucleus. These pyrimidines are: uracil, thymine and cytosine. Recent ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

Fluorescent nucleobases are chemically modified DNA and RNA analogues that not only retain their chemical and biological functionalities, such as stacking, base pairing and enzyme incorporation, but ...

In vitro "glycorandomization" is a chemoenzymatic approach for generating diverse libraries of glycosylated biomolecules based on natural product scaffolds. This technology makes use of engineered ...
