Partial purification of cytidine deaminase from protoscoleces of Echinococcus granulosus [PDF]
Cytidine deaminase (EC 3.5.4.5) has been partially purified from protoscoleces of Echinococcus granulosus by gel filteration chromatography using Sephadex G200 .The molecular weight of the enzyme determined by gel filteration was about 82000 dalton with ...

Programmable base editing of zebrafish genome using a modified CRISPR-Cas9 system. [PDF]
Precise genetic modifications in model animals are essential for biomedical research. Here, we report a programmable "base editing" system to induce precise base conversion with high efficiency in zebrafish. Using cytidine deaminase fused to Cas9 nickase,

Natural variation in Vif: differential impact on APOBEC3G/3F and a potential role in HIV-1 diversification. [PDF]
The HIV-1 Vif protein counteracts the antiviral activity exhibited by the host cytidine deaminases APOBEC3G and APOBEC3F. Here, we show that defective vif alleles can readily be found in HIV-1 isolates and infected patients. Single residue changes in the

Phosphorylation of purine and pyrimidine nucleosides by isolated rat liver mitochondria [PDF]
Formation of 5'-AMP, 5'-GMP, 5'-CMP and 5'UMP was confirmed in isolated rat liver mitochondria incubated with alpha-ketoglutarate, inorganic phosphate, purine nucleoside and pyrimidine nucleoside. Increased incorporation of 32Pi into ATP, GTP and UTP was

Population level analysis of human immunodeficiency virus type 1 hypermutation and its relationship with APOBEC3G and vif genetic variation [PDF]
APOBEC3G and APOBEC3F restrict human immunodeficiency virus type 1 (HIV-1) replication in vitro through the induction of G!92A hypermutation; however, the relevance of this host antiviral strategy to clinical HIV-1 is currently not known.

Adenosine to inosine editing by ADAR2 requires formation of a ternary complex on the GluR-B R/G site [PDF]
RNA editing by members of the ADAR (adenosine deaminase that acts on RNA) enzyme family involves hydrolytic deamination of adenosine to inosine within the context of a double-stranded pre-mRNA substrate.
