Isolation of Nucleoside Metabolizing Enzymes from Alaska Pea Seeds (Pisum sativum L. cultivar Alaska) [PDF]

open access: yes, 2013
The activities of number of metabolizing enzymes were determined from dry Alaska Pea Seeds (Pisum sativum L. cultivar Alaska). Then tested for presence of three groups of enzymes; nucleosidase, deaminases and phosphorylases. The highest activity of the

NUCLEOSIDE CATABOLIZING ACTIVITIES IN SELECTED SEEDS [PDF]

open access: yes, 2016
The efficacy of pyrimidine and purine nucleotide metabolism plays a critical role in the progression of biological systems. The process of nucleotide degradation exists in all organisms. The nucleoside degradation and salvage of nucleotides, nucleosides,

Human APOBEC1 cytidine deaminase edits HBV DNA [PDF]

open access: yes, 2009
Retroviruses, hepadnaviruses, and some other retroelements are vulnerable to editing by single stranded DNA cytidine deaminases. Of the eleven human genes encoding such enzymes, eight have demonstrable enzymatic activity.

Bacterial cytidine deaminases as versatile activators of fluoropyrimidine nucleoside prodrugs

open access: yesEuropean Journal of Medicinal Chemistry
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.

An Overview of ADAR Inhibitors: Mechanisms, Applications, and Future Directions [PDF]

open access: yes
Adenosine deaminases acting on RNA (ADARs) are enzymes responsible for converting adenosine to inosine in double-stranded RNA through a process known as A-to-I editing.
