(whale.to)
  • Understanding the binding specificity of a DNA binding protein is helpful for the research of protein functions. (biomedcentral.com)
  • Though there are some researches [ 5 - 7 ] on the SSB and DSB respectively, few attentions have been paid on investigating what makes SSB and DSB have such different kind of binding specificity. (biomedcentral.com)
  • Since direct fluorescence monitoring is difficult due to the opacity of serum, denaturing and nondenaturing gel electrophoresis were combined for studying the interaction between serum proteins and DNAzymes. (uwaterloo.ca)
  • PARP-1 is the best-characterized member of the diphtheria toxin-like ADP-ribosyl transferases (ARTDs) family of proteins. (nature.com)
  • The purine-rich element binding (Pur) protein family protein consists PURalpha/beta/gamma in humans. (embl-heidelberg.de)
  • More recently, the application of RNA-seq technologies has enabled the elucidation of the biological partners and targets of several ProQ/FinO family proteins. (nature.com)
  • While these studies have built the case that certain ProQ/FinO family members bind to only a very limited number of partners in a highly specific manner, other family members appear to have multiple biological sRNA targets. (nature.com)
  • Belongs to the ATP-dependent DNA ligase family. (lu.se)
  • Domain analysis of this protein, which contains a single OB fold, showed that its architecture is similar to the functional homologs thought to be unique to the Crenarckaeotes. (johnshopkins.edu)
  • DNA/RNA-binding repeats in PUR-alpha/beta/gamma and in hypothetical proteins from spirochetes and the Bacteroides-Cytophaga-Flexibacter bacteria. (embl-heidelberg.de)
  • The RRM structure consists of four strands and two helices arranged in an alpha/beta sandwich, with a third helix present during RNA binding in some cases. (embl.de)
  • Predicted to enable DNA binding activity and nuclease activity. (mcw.edu)
  • Similarly, a minimal ProQ/FinO domain protein, NMB1681, has been shown to bind a range of structured RNAs in Neisseria meningitidis 15 . (nature.com)
  • Two Ets proteins, PU.1 and elf-1, that have previously been shown to bind to an adjacent DNA element were shown to physically interact with CArG- box binding factor.A. An antiserum raised against the protein recognized two different forms indicating either that different splice-forms of. (lu.se)

  • Recently, we have demonstrated high-bandwidth detection of double-stranded (ds) DNA with microsecond time resolution in nanopipettes, using custom-designed electronics. (imperial.ac.uk)
  • With this understanding, the detection of DNA using the 17E DNAzyme is demonstrated in serum. (uwaterloo.ca)
  • Insight into how these proteins recognize their cognate RNAs initiated with FinO. (nature.com)
  • Degradation of both the substrate and the DNAzyme strand is very slow in serum, especially at room temperature. (uwaterloo.ca)
  • Source of all serum proteins is from USDA inspected abattoirs located in the United States. (bdbiosciences.com)
  • It has a structure of three beta-strands to a single six-stranded beta-sheet to form a protein dimer. (wikipedia.org)
  • However, the most common form is a protein with two OB folds and one zinc finger domain. (johnshopkins.edu)
  • Although the diversity shown by archaeal single-stranded DNA-binding proteins is unparalleled, the presence of their simplest form in many organisms across all domains of life is of greater evolutionary consequence. (johnshopkins.edu)
  • They then unfold themselves to form the DNA strands. (whale.to)
