Torque and temperature dependence of the hysteretic voltage-induced torsional strain in tantalum trisulfide

open access: yes, 2011
We have measured the dependence of the hysteretic voltage-induced torsional strain (VITS) in crystals of orthorhombic tantalum trisulfide on temperature and applied torque.

A ribose-functionalized NAD+ with unexpected high activity and selectivity for protein poly-ADP-ribosylation. [PDF]

open access: yes, 2019
Nicotinamide adenine dinucleotide (NAD+)-dependent ADP-ribosylation plays important roles in physiology and pathophysiology. It has been challenging to study this key type of enzymatic post-translational modification in particular for protein poly-ADP ...

Analysis of ligation and DNA binding by Escherichia coli DNA ligase (LigA). [PDF]

open access: yes, 2005
NAD+-dependent DNA ligases are essential enzymes in bacteria, with the most widely studied of this class of enzymes being LigA from Escherichia coli. NAD+-dependent DNA ligases comprise several discrete structural domains, including a BRCT domain at the ...

Nicotinamide adenine dinucleotide extends the lifespan of Caenorhabditis elegans mediated by sir-2.1 and daf-16 [PDF]

open access: yes, 2010
It is well understood that sir2 (sirtuin), an NAD-dependent deacetylase, is essential for the extension of lifespan under caloric restriction. However, the mechanism underlying activation of sir2 is unclear.

Characterization of the human omega-oxidation pathway for omega-hydroxy-very-long-chain fatty acids [PDF]

open access: yes, 2008
Very-long-chain fatty acids (VLCFAs) have long been known to be degraded exclusively in peroxisomes via beta-oxidation. A defect in peroxisomal beta-oxidation results in elevated levels of VLCFAs and is associated with the most frequent inherited ...
