Nucleoside analog studies indicate mechanistic differences between RNA-editing adenosine deaminases [PDF]
Adenosine deaminases acting on RNA (ADAR1 and ADAR2) are human RNA-editing adenosine deaminases responsible for the conversion of adenosine to inosine at specific locations in cellular RNAs. Since inosine is recognized during translation as guanosine, this often results in the expression of protein sequences different from those encoded in the genome ...

Bacterial cytidine deaminases as versatile activators of fluoropyrimidine nucleoside prodrugs
A platform for modification of 5-fluoropyrimidine nucleosides as potential prodrugs has been developed utilizing bacterial-derived cytidine deaminases (CDAs) for activation. It has been demonstrated that CDA_EH, CDA_F14, and CDA_Lsp effectively convert 5-fluoropyrimidine analogs into 5-fluoro-(2′-deoxy)uridine exhibiting cytotoxic effects.

DNA editing in DNA/RNA hybrids by adenosine deaminases that act on RNA. [PDF]
Adenosine deaminases that act on RNA (ADARs) carry out adenosine (A) to inosine (I) editing reactions with a known requirement for duplex RNA. Here, we show that ADARs also react with DNA/RNA hybrid duplexes.

Trading in cooperativity for specificity to maintain uracil-free DNA [PDF]
Members of the dUTPase superfamily play an important role in the maintenance of the pyrimidine nucleotide balance and of genome integrity. dCTP deaminases and the bifunctional dCTP deaminase-dUTPases are cooperatively regulated by dTTP.

Probing RNA recognition by human ADAR2 using a high-throughput mutagenesis method. [PDF]
Adenosine deamination is one of the most prevalent post-transcriptional modifications in mRNA. In humans, ADAR1 and ADAR2 catalyze this modification and their malfunction correlates with disease. Recently our laboratory reported crystal structures of the

Expanding a fluorescent RNA alphabet: synthesis, photophysics and utility of isothiazole-derived purine nucleoside surrogates. [PDF]
A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe-Ziegler cyclization.
