VEZF1 elements mediate protection from DNA methylation [PDF]
There is growing consensus that genome organization and long-range gene regulation involves partitioning of the genome into domains of distinct epigenetic chromatin states.

CDT1 is an essential protein for DNA replication licensing that loads the MCM complex, the eukaryotic replicative DNA helicase, onto replication origins. Overexpression of CDT1 induces cell cycle arrest at the S phase. Here we showed CDT1 inhibits the progression of replication forks by interacting with the MCM complex, leading to the stalling and ...

DNA single-strand break repair and spinocerebellar ataxia with axonal neuropathy-1 [PDF]
DNA single-strand breaks (SSBs) are the commonest DNA lesions arising spontaneously in cells, and if not repaired may block transcription or may be converted into potentially lethal/clastogenic DNA double-strand breaks (DSBs).

Recombinant Human DNA (Cytosine-5) Methyltransferase
A method is described to express and purify human DNA (cytosine-5) methyltransferase (human DNMT1) using a protein splicing (intein) fusion partner in a baculovirus expression vector. The system produces ∼1 mg of intact recombinant enzyme >95% pure per 1.

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification
The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow

DNA replication and recombination [PDF]
Knowledge of the structure of DNA enabled scientists to undertake the difficult task of deciphering the detailed molecular mechanisms of two dynamic processes that are central to life: the copying of the genetic information by DNA replication, and its reassortment and repair by DNA recombination.

Expression in mammalian cells of a cloned gene encoding murine DNA methyltransferase [PDF]
Mammalian DNA cytosine-5-methyltransferase (MTase, EC 2.1.1.37) is an essential component for establishing and maintaining cell-type specific methylation patterns in the genome. The cDNAfor the murine enzyme was previously cloned in segments.
