Serum adenosine deaminase and cytidine deaminase activities in patients with systemic lupus erythematosus

open access: yes, 2002
We evaluated serum total adenosine deaminase, its isoenzymes adenosine deaminase-1 and adenosine deaminase-2, and cytidine deaminase activities in 24 patients with active systemic lupus erythematosus, and in 26 healthy control subjects, and found the ...

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Gender effects on cytidine analogue metabolism and myelodysplastic syndrome treatment outcomes [PDF]

open access: yes, 2012
In vivo, half-lives of cytidine analogues such as 5-azacytidine and decitabine, used to treat myelodysplastic syndromes (MDS), are determined largely by cytidine deaminase (CDA), an enzyme that rapidly metabolizes these drugs into inactive uridine ...

A role for Tau protein in maintaining ribosomal DNA stability and cytidine deaminase-deficient cell survival [PDF]

open access: yes, 2018
Cells from Bloom's syndrome patients display genome instability due to a defective BLM and the downregulation of cytidine deaminase. Here, we use a genome-wide RNAi-synthetic lethal screen and transcriptomic profiling to identify genes enabling BLM ...

Human placenta cytidine deaminase: a zinc metalloprotein [PDF]

open access: yesIUBMB Life, 1997
AbstractCytidine deaminase, a tetrameric enzyme purified from human placenta, was shown to contain a single atom of tightly bound zinc per subunit by Inductively Coupled Plasma Optical Emission Spectrometry analysis. The metal appears to be involved in catalysis, as suggested by the inhibition exerted by 1,10‐phenanthroline and dipicolinic acid.

Targeting Tex10 Overcomes Oxaliplatin Resistance by Competitively Disrupting the Non‐Canonical BAF Complex in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
This study reveals that Tex10 drives oxaliplatin resistance in colorectal cancer by competitively binding BRD9 to disrupt the ncBAF complex, thereby suppressing AMBRA1 transcription and ULK1‐mediated autophagy. Gemcitabine is identified as a direct Tex10 inhibitor that restores autophagy and overcomes resistance.

Regulation of activation induced deaminase [PDF]

open access: yes, 2009
Activation Induced Deaminase (AID) belongs to the protein family of DNA deaminases, which catalyse the deamination of the cytosine residues in single stranded DNA, resulting in the formation of deoxy-uracils.

Continuous Evolution System Based on Toxin–Antitoxin System Combined with Base Deaminase Accelerates the In Vivo Modification of Target Proteins

open access: yesAdvanced Science, EarlyView.
The promoted Escherichia coli‐assisted continuous evolution (PEACE) system operates through a stringent three step genetic circuit: target gene mutation via a deaminase–T7 RNA polymerase (T7 RNAP) fusion, coupling variant function to antitoxin expression, and growth based selection of surviving cells.

Crystal structure of the catalytic domain of HIV-1 restriction factor APOBEC3G in complex with ssDNA

open access: yesNature Communications, 2018
APOBEC3G (A3G) is a single-stranded DNA (ssDNA) cytidine deaminase that restricts HIV-1. Here the authors provide molecular insights into A3G substrate recognition by determining the 1.86 Å resolution crystal structure of its catalytic domain bound to ...

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

open access: yesAdvanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.
