An agar medium combining dulcitol fermentation, malonate utilization, and phenylalanine deamination was evaluated with 229 isolates representing 19 genera. All reactions agreed with those obtained on conventional media.
We report that deamination coupled with 5-carboxyvinyldeoxyuridine-mediated photobranching causes the heat-induced transition of cytosine to uracil with high efficiency without any side reaction.
The prokaryotic DNA(cytosine-5)methyltransferase M.SssI shares the specificity of eukaryotic DNA methyltransferases (CG) and is an important model and experimental tool in the study of eukaryotic DNA methylation. Previously, M.SssI was shown to be able to catalyze deamination of the target cytosine to uracil if the methyl donor S-adenosyl-methionine (SAM) was missing from the reaction. To test ...
BACKGROUND Editing deaminases have a pivotal role in cellular physiology. A notable member of this superfamily, APOBEC3G (A3G), restricts retroviruses, and Activation Induced Deaminase (AID) generates antibody diversity by localized deamination of cytosines in DNA. Unconstrained deaminase activity can cause genome-wide mutagenesis and cancer. The mechanisms that protect the genomic DNA from the...
