Cysteine Methylation Controls Radical Generation in the Cfr Radical AdoMet rRNA Methyltransferase [PDF]
The 'radical S-adenosyl-L-methionine (AdoMet)' enzyme Cfr methylates adenosine 2503 of the 23S rRNA in the peptidyltransferase centre (P-site) of the bacterial ribosome.

Biphasic kinetics of the human DNA repair protein MED1 (MBD4), a mismatch-specific DNA N-glycosylase
The human protein MED1 (also known as MBD4) was previously isolated in a two-hybrid screening using the mismatch repair protein MLH1 as a bait, and shown to have homology to bacterial base excision repair DNA N-glycosylases/lyases.

Rrp47p is an exosome-associated protein required for the 3 ' processing of stable RNAs [PDF]
Related exosome complexes of 3'-->5' exonucleases are present in the nucleus and the cytoplasm. Purification of exosome complexes from whole-cell lysates identified a Mg2+-labile factor present in substoichiometric amounts. This protein was identified

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA [PDF]
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

The kinetics of uracil-N-glycosylase distribution inside replication foci
Mismatched nucleobase uracil is commonly repaired through the base excision repair initiated by DNA uracil glycosylases. The data presented in this study strongly indicate that the nuclear uracil-N-glycosylase activity and nuclear protein content in ...

N-Glycosyl Bond Formation Catalyzed by Human Alkyladenine DNA Glycosylase
The removal of damaged bases by DNA glycosylases is thought to be effectively irreversible, because of an overall equilibrium that favors hydrolysis over synthesis of the N-glycosyl bond.

DNA Glycosylase Activity Assay Based on Streptavidin Paramagnetic Bead Substrate Capture
A method to detect DNA glycosylase activity is described. The substrate used was an oligodeoxyribonucleotide with a unique hypoxanthine base, but has general application to any DNA glycosylase or endonuclease.
