  • Based on the data presented here, we propose a model for xylan degradation by P. cellulosa in which the GH11 enzymes convert decorated xylans into substituted xylooligosaccharides, which are then hydrolyzed to their constituent sugars by the combined action of cell-associated GH10 xylanases and side chain-cleaving enzymes.

  • AAV2 containing cDNA encoding enhanced green fluorescent protein (GFP), under the control of a chicken β-actin promoter, was delivered by intravitreal injection to adult mice in conjunction with enzymes including collagenase, hyaluronan lyase, heparinase III, or chondroitin ABC lyase. (molvis.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)
  • The enzymes act sequentially, first converting the peptidylglycine substrate into a short-lived peptidyl-α-hydroxyglycine intermediate and then cleaving the C-N bond to produce the amidated peptide and glyoxylate [ 2 ]. (biomedcentral.com)
  • more specifically the ox-acid-lyase or the carbon-carbon-lyases. (wikipedia.org)
  • compared to other polysaccharide lyases such as pectate lyases, which tend to have rather basic pH optima. (cazypedia.org)
  • Another major difference to the pectate and other polysaccharide lyase mechanisms, is that divalent metal ions are not required by PL4 for catalysis. (cazypedia.org)
  • which despite belonging to [[PL1]], have diverged significantly from the pectate lyases. (cazypedia.org)
  • Of the three tail spikes, two have protein domains associated with the pectate lyase family of proteins (Tsp2) and P22 tail spike family (Tsp3) with the prospect that these enable Salmonella O antigen degradation. (biomedcentral.com)
  • The enzyme chorismate lyase (EC 4.1.3.40) catalyzes the first step in ubiquinone biosynthesis, the removal of pyruvate from chorismate, to yield 4-hydroxybenzoate in Escherichia coli and other Gram-negative bacteria. (wikipedia.org)
  • The systematic name of this enzyme class is chorismate pyruvate-lyase (4-hydroxybenzoate-forming). (wikipedia.org)
  • In addition, L-cysteine can be converted into hydrogen sulfide and pyruvic acid through the action of the enzyme cystathionine gamma-lyase. (cannabisdatabase.ca)
  • removal activating the enzyme. (wikipedia.org)
  • Removal of this region by proteolytic cleavage results in activation of the enzyme . (wikipedia.org)
  • For instance it can bind a cofactor to a ligand or cleave between amino acids. (proteogenix.science)
  • Note: The Mut proteins, S and L, recognize the mismatch and identify the parental (methylated) strand, and Mut H cleaves the daughter strand. (pharmacy180.com)
  • Macroautophagy, hereafter referred to as autophagy, is a lysosomal degradative process that participates in cellular homeostasis by enabling the removal of defective organelles, protein aggregates, or intracellular microorganisms ( 1 ). (frontiersin.org)
  • In this case, merB cleaves the carbon-mercury bonds of organomercuric compounds via protonolysis and forms a mercury dithiolate complex. (projectguru.in)
  • Treatment involves compounds that increase the removal of nitrogen waste. (medscape.com)
  • Xyn11A, but not Xyn11B, exhibits xylan esterase activity, and the removal of acetate side chains is required for xylanases to hydrolyze the xylan backbone. (omicsdi.org)
  • In addition to oxidase or reductase, this class contains dehydrogenases that are responsible for hydrogen removal. (proteogenix.science)
  • 4. Formation or removal of a double bond with group transfer. (cliffsnotes.com)
  • However, although each solitary mutation favorably affects cleft stability, the phenotype of the double mutant is clearly synergistic. (bioskinrevive.com)
  • Furthermore, H2S therapy flight delays pectin wreckage throughout the safe-keeping period as well as significantly downregulated the particular expression involving genes computer programming with regard to pectinases, including polygalacturonase, pectate lyase, and expansin. (nitazoxanideinhibitor.com)
  • A damaged base is recognized by a specific DNA glycosylase, which cleaves the bond between the base and sugar, creating an abasic site (AP), which is a mutagenic and cytotoxic intermediate. (springer.com)
  • The AP endonucleases cleave an AP site to yield a 3′ hydroxyl adjacent to a 5′ deoxyribosephosphate (dRP). (springer.com)
  • We have recently characterized the additional presence of an unexpected 5'-2-deoxyribose-5-phosphate (dRP) lyase activity in the ligase domain (LigDom) of the LigD from B. subtilis and P.aeruginosa . (uam.es)
  • The resulting AP site is further processed by the AP lyase activity associated with bifunctional DNA glycosylases and AP endonucleases cleaving 3′or 5′at the AP site, respectively. (springer.com)
  • Non-hydrolytic addition or removal of groups from substrates. (wikipedia.org)
  • The iron-sulphur cluster loop (FCL) is also found in DNA-(apurinic or apyrimidinic site) lyase, a subfamily of endonuclease III. (embl-heidelberg.de)
  • Therefore, we present EMBR-seq+, which requires fewer than ten oligonucleotides per rRNA by combining rRNA blocking primers with RNase H-mediated depletion to achieve rRNA removal efficiencies of up to 99% in diverse bacterial species. (biorxiv.org)
  • Furthermore, these results suggest that the FCL motif is intimately involved in the base removal process. (embl-heidelberg.de)
