Archaeal diversity in deep-sea sediments estimated by means of different Terminal-Restriction Fragment Length Polymorphisms (T-RFLP) protocols [PDF]
, 2009 Despite the increasing recognition of the quantitative importance of Archaea in all marine systems, the protocols for a rapid estimate of Archaeal diversity patterns in deep-sea sediments have been only poorly tested yet.

The Architecture of Restriction Enzymes [PDF]
Structure, 2013 In this issue of Structure, Lyumkis and colleagues describe a high resolution structure of a polymerized form of the SgrAI restriction enzyme, which shows that it forms a helical assembly with four enzyme molecules per turn of the helix. The DNA is arranged on the periphery of the protein helix pointing away from the helical axis.

Pathological phenotypes and in vivo DNA cleavage by unrestrained activity of a phosphorothioate-based restriction system in Salmonella [PDF]
, 2014 Prokaryotes protect their genomes from foreign DNA with a diversity of defence mechanisms, including a widespread restriction–modification (R–M) system involving phosphorothioate (PT) modification of the DNA backbone. Unlike classical R–M systems, highly

Characterization of Ascaris from Ecuador and Zanzibar [PDF]
, 2014 To shed light on the epidemiology of ascariasis in Ecuador and Zanzibar, 177 adult worms retrieved by chemo-expulsion from either people or pigs were collected, measured and subjected to polymerase chain reaction-restriction fragment length polymorphism (

A Sliding Restriction Enzyme Pauses [PDF]
Structure, 2007 In this issue of Structure, Aggarwal and colleagues (Townson et al., 2007) present the crystal structure of the restriction endonuclease BstYI in complex with a near-cognate substrate. This structure most likely reflects the conformation BstYI adopts as it scans DNA and pauses upon encountering a site similar to its recognition sequence.
