Nucleoside deaminases: the key players in base editing toolkit. [PDF]
Biophys Rep, 2023 The development of nucleoside deaminase-containing base editors realized targeted single base change with high efficiency and precision. Such nucleoside deaminases include adenosine and cytidine deaminases, which can catalyze adenosine-to-inosine (A-to-I) and cytidine-to-uridine (C-to-U) conversion respectively.

Distinct Phage‐Encoded Enzymes for Substitution of Deoxythymidine by Deoxyuridine in Phage Genomes [PDF]
Advanced Science, Volume 12, Issue 46, December 11, 2025.Distinct enzymes including dCTP deaminases (Dcds), dTMP phosphatases (Dtms), and dTTP pyrophosphatases (Dtt) are found to be responsible for dU‐DNA biosynthesis in the phages PBS1, DSS3_VP1, and PhiR1‐37. Both PhiR1‐37‐derived and synthetic dU‐DNA are resistant to cleavage by restriction enzymes and Cas12a nuclease targeting dT‐containing sites.

Direct Sequencing of 5‐Methylcytosine and 5‐Hydroxymethylcytosine at Single‐Base Resolution Unravels Their Distinct Roles in Alzheimer's Disease [PDF]
Advanced Science, Volume 12, Issue 38, October 13, 2025.This study introduces two orthogonal sequencing methods, CMD1‐Deaminase sequencing (CD‐seq) and CMD1‐TET bisulfite sequencing (CT‐seq), that enable direct, independent detection of 5mC. Using these approaches together with ACE‐seq or TAB‐seq for 5hmC identification, the study reveals a significant reduction in 5hmC, but not 5mC, in the hippocampus of ...

DNA editing in DNA/RNA hybrids by adenosine deaminases that act on RNA. [PDF]
, 2017 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]
, 2015 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]
, 2016 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
