  • T4 DNA ligase is one of the workhorses of molecular biology and used in various biotechnological applications. Here we report that this ligase, unlikeEscherichia coliDNA ligase,TaqDNA ligase and Ampligase, is able to join the ends of single-stranded DNA in the absence of any duplex DNA structure at the ligation site.

  • Reactive oxygen species (ROS) are products of normal metabolic activities and are thought to be the cause of many diseases. A selenium-containing single-chain abzyme 2F3 (Se-2F3-scFv) that imitates glutathione peroxidase has been produced which has the capacity to remove ROS. To evaluate the antioxidant ability of Se-2F3-scFv, we con-structeda ferrous sulfate/ascorbate (Vc/Fe 2+ )-inducedmito-chondrial damage model system and investigated the capacity of Se-2F3-scFv to protect mitochondria from oxi-dative damage.

  • Single crystal X-ray crystallography is the most common and easily accessible way to determine the molecular structure of any crystalline material. This method provides two kinds of information which are needed for understanding both single molecule properties and bulk material properties: 1. Molecular Structure - Single Molecules: Unambiguous and three-dimensional information about the structure of the molecular entities.

  • There have been several significant advances innuclearmedicine since the publication of the second edition of Practical NuclearMedicine. The last seven years have seen great strides in instrumentation, including new coincidence detectors, the development of a wider variety of crystals, and the advent of combined anatomical/functional imaging devices, including PET/CT and SPECT/CT. PET imaging with 18F-FDG has become a mainstay of many clinical settings, and other radiotracers are finding theirway into the rapidly expanding field of oncologic PET.

  • Salvinorin A is a potent kappa opioid receptor (KOP) agonist with unique structural and pharmacological properties. This non-nitrogenous ligand lacks nearly all the structural features commonly associated with opioid ligand binding and selectivity. This study explores the structural basis to salvinorin A binding and selectivity using a combination of chimeric and single-point mutant opioid receptors.

  • Ascorbic acid is often regarded as an antioxidantin vivo, where it protects against cancer by scavenging DNA-dam-aging reactive oxygen species. However, the detailed mech-anism of the action of ascorbic acid on genetic DNA is still unclear. We examined the effect of ascorbic acid on the higher-order structure of DNA through real-time observa-tion by fluorescence microscopy. We found that ascorbic acid generates a pearling structure in single giant DNA molecules, with elongated and compact regions coexisting along a molecular chain. ...

  • Single-crystal X-ray structure determinations of the complex between the minor-groove binder distamycin and d(GGCCAATTGG) reveal two 1 : 1 binding modes which differ in the orientation of the drug molecule in the minor groove. The two crystals were grown from different crystallization conditions and found to diffract to 2.38 and ˚ 1.85 A, respectively. The structures were refined to completion using SHELXL-93, resulting in a residual R factor of ˚ 20.30% for the 2.38-A resolution structure (including 46 ˚ water molecules) and 19.74% for the 1.

  • The thermodynamic stability of family 16 endo-b-1,3-glucanase (EC 3.2.1.39) from the hyperthermophilic archaeon Pyrococcus furiosusis decreased upon single (D287A, E53A) and double (E53A⁄D287A) muta-tion of Asp287 and Glu53. In accordance with the homology model predic-tion, both carboxylic acids are involved in the composition of a calcium binding site, as shown by titration of the wild-type and the variant proteins with a chromophoric chelator.

  • Filamentous ascomycetes harbor Woronin bodies and glyoxysomes, two types of microbodies, within one cell at the same time. The dominant pro-tein of the Neurospora crassaWoronin body, HEX1, forms a hexagonal core crystal via oligomerization and evidence has accumulated that Woro-nin bodies bud off from glyoxysomes.

  • In the past, protease-substrate finding proved to be rather haphazard and was executed byin vitro cleavage assays using singly selected targets. In the present study, we report the first protease proteomic approach applied to meprin, an astacin-like metalloendopeptidase, to determine physiological substrates in a cell-based system of Madin–Darby canine kidney epithelial cells.
