Parallel Implementation of MAFFT on CUDA-Enabled Graphics Hardware present a new approach to accelerat- ing MAFFT on Graphics Processing Units (GPUs) using the Compute Unified Device Architecture (CUDA) programming model. Compared with the implementations of other MSA algorithms on GPUs, parallelization of MAFFT is more challenging since the space complexity.

Theoxidation-promotingreactivityof copper(II) complexof aminoglycosidic antibiotic amikacin [Cu(II)-Ami] in the presence of hydrogen peroxide, was studied at pH 7.4, using 2¢-deoxyguanosine (dG), pBR322 plasmid DNA and yeast tRNA Phe as target molecules. Themixtures of complexwith H2O2were found to be efficient oxidants, converting dG to its 8-oxo derivative, generating strand breaks in plasmid DNA and multiple cleavages in tRNA Phe .

The pyruvate dehydrogenase complex (PDC) is subjected to multiple interacting levels of control in plant cells. The first level is subcellular compartmentation. Plant cells are unique inhaving twodistinct, spatially separated forms of the PDC; mitochondrial (mtPDC) and plastidial (plPDC). The mtPDCis the site of carbon entry into the tricarboxylic acid cycle, while the plPDCprovides acetyl-CoAandNADHfor de novofatty acid biosynthesis.

Limitedproteolysis of the pyruvate decarboxylase (E1,a2b2 ) component of the pyruvate dehydrogenase (PDH) multi-enzyme complexofBacillus stearothermophilushas indicated the importance for catalysis of a site (Tyr281-Arg282) in the E1asubunit (Chauhan, H.J., Domingo, G.J., Jung, H.-I. & Perham, R.N. (2000)Eur. J. Biochem.267, 7158–7169). This site appears to be conserved in the a-subunit of hetero-tetrameric E1s and multiple sequence alignments suggest that there are additional conserved amino-acid residues in this region, part of a common pattern with the consensus sequence -YR-H-D-YR-DE-.

The protein tyrosine phosphatase PTP-Basophil (PTP-Bas) and itsmouse homologue, PTP-Basophil-like (PTP-BL), are high molecular mass protein phosphatases consisting of a number of diverse protein–protein interaction modules. Several splicing variants of these phosphatases are known to exist thus demonstrating the complexity of these molecules. PTP-Bas/BL serves as a central scaffolding protein facilita-ting the assembly of a multiplicity of different proteins mainly via five different PDZ domains. ...

Recently, the CPS biosynthetic loci for several strains ofCampylobacter jejuni were sequenced and revealed evidence for multiple mechanisms of structural variation. In this study, the CPS structure for the HS:1 serostrain of C. jejuni was determined using mass spectrometry and NMR at 600 MHz equipped with an ultra-sensitive cryogenically cooled probe. Ana-lysis of CPS purified using a mild enzymatic method revealed a teichoic acid-like [-4)-a-d-Galp-(1–2)-(R)-Gro-(1-P]n, repeating unit, where Gro is glycerol....

Functional diversity of potassium channels in both prokaryotic and euk-aryotic cells suggests multiple levels of regulation. Posttranslational regula-tion includes differential subunit assembly of homologous pore-forming subunits. In addition, a variety of modulatory subunits may interact with the pore complex either statically or dynamically. Kv2.1 is a delayed recti-fier potassium channel isolated by expression cloning.

The pyruvate dehydrogenase complex occupies a central and strategic posi-tion in muscle intermediary metabolism and is primarily regulated by phos-phorylation⁄dephosphorylation. The identification of multiple isoforms of pyruvate dehydrogenase kinase (PDK1–4) and pyruvate dehydrogenase phosphatase (PDP1–2) has raised intriguing new possibilities for chronic pyruvate dehydrogenase complex control.

Overall, the pathway is subject to intramito-chondrial control at multiple sites. However, at least in the liver, carnitine palmitoyl transferase I exerts approximately 80% of control over pathway flux under normal conditions....

Ribosomal protein S6 kinase (S6K) is activated by an array of mitogenic stimuli and is a key player in the regulation of cell growth. The activation process of S6 kinase involves a complex and sequential series of multiple Ser⁄Thr phosphorylations and is mainly mediated via phosphatidylinositol 3-kinase (PI3K)-3-phosphoinositide-dependent protein kinase-1 (PDK1) and mTor-dependent pathways.

The innate immune system has provided an excellent model for study-ing complex regulatory networks at the levels of signal transduction and transcription. Virus infection of mammalian cells triggers the coor-dinate activation of multiple signaling pathways leading to the activa-tion of specific sets of transcription factors that assemble on the interferon-b (IFN-b) gene enhancer to form an enhanceosome.
