  • First, the sequences carrying point mutations are modeled on a given template structure, and subsequently, molecular dynamics simulations are carried out for 10 ns. (hindawi.com)
  • They recognize long asymmetric nucleotide sequences and cleave both DNA strands in a monomer form. (rcsb.org)
  • An example of enzymes that bind a single substrate and release multiple products are proteases , which cleave one protein substrate into two polypeptide products. (wikipedia.org)
  • Amino-acid sequence and structure comparison suggested that the enzyme belongs to a group of enzymes classified as archaeal Holliday junction-resolving enzymes, which are typically divalent metal ion-binding dimers that are able to cleave X-shaped dsDNA-Holliday junctions (Hjs). (iucr.org)
  • The precise regulations of pre-RC protein levels and assembly are effective ways to prevent reassembly of de novo MCM2-7 onto the replicated origins to re-license and re-replicate the genomic DNA in the subsequent phases of the same cell cycle ( Figure 1) . (intechopen.com)
  • In epipelagic SAR324 ecotypes, we observed the presence of two types of proton-pumping rhodopsins, as well as genomic, transcriptomic, and ecological evidence for active photoheterotrophy, based on xanthorhodopsin-like light-harvesting proteins. (biomedcentral.com)
  • Since fMet is present in proteins made by mitochondria and chloroplasts, more recent theories do not see it as a molecule that the immune system can use to distinguish self from non-self. (wikipedia.org)
  • In Escherichia coli , amino acid starvation leads to the accumulation of an unusual molecule, polyphosphate (polyP), a linear polymer of many hundreds of orthophosphate residues. (go.jp)
  • Glycosyltransferases (GTs) are enzymes that synthesize oligosaccharides, polysaccharides, and glycoconjugates by transferring the sugar moiety from an activated nucleotide-sugar donor to an acceptor molecule, which may be a growing oligosaccharide, a lipid, or a protein. (unl.edu)
  • Digestion breaks the proteins down for use in the metabolism. (transectscience.org)
  • Briefly, calibrators, quality controls, a matrix blank, blind QCs, and NHANES samples were prepared by performing a protein digestion using pronase to release the chlorinated tyrosine biomarkers. (cdc.gov)
  • After digestion, any undigested proteins were removed by protein precipitation. (cdc.gov)
  • Cellulose is an aggregate of unbranched polymers of beta-1,4-linked glucose residues, which is an abundant polysaccharide produced by plants and in varying degrees by several other organisms including algae, bacteria, fungi, and even some animals. (unl.edu)
  • A). stress inhibitor tauroursodeoxycholate (TUDCA) or glucose-regulated protein 78?kDa (GRP78) depletion significantly abrogated the effect of eHSP90 on ER stress and fibroblast activation. (healthanddietblog.info)
  • Polymorphonuclear cells can bind proteins starting with fMet, and use them to initiate the attraction of circulating blood leukocytes and then stimulate microbicidal activities such as phagocytosis . (wikipedia.org)
