Example sentences for: catalysis

How can you use “catalysis” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Residues in subdomains VIB and VII are directly involved in catalysis and only the most conservative substitutions would be consistent with enzymatic activity.

  • The conserved charged and polar residues conceivably might be involved in catalysis and substrate-binding.

  • NTPDases do not form phosphorylated intermediates during catalysis, a conclusion also supported by lack of vanadate sensitivity and Pi product inhibition [ 3 4 5 6 ] . The catalytic reaction appears to be irreversible and no partial reactions have been observed [ 7 8 ] . Divalent cations like Ca 2+or Mg 2+are required for activity, and maximal activity is reached when the concentrations of substrates and divalent cations are equal [ 1 ] . The specific activities of NTPDases vary over a broad range from ten thousand units for potato apyrase to less than one hundred units for chicken gizzard ecto-ATPase [ 9 10 ] . Sequence comparisons indicate that most of NTPDases contain five highly conserved regions, apyrase conserved region, ACR1 - ACR5 [ 9 11 ] . However, the catalytic sites have not been identified, although ACR1 and ACR4 have been implicated in β- and γ-phosphate binding, respectively [ 9 ] .

  • The 3' approach to the DNA [ 34 ] and the wide area covered by the protein on both sides of the abasic site [ 14 ] are both consistent with the need to hold the product until the correct polymerase moves in 5' to 3' to complete the repair [ 25 ] . This implies that the mammalian enzyme has evolved to be processive, to facilitate more efficient functioning of the overall BER pathway, and may not be optimized for simple catalysis.

  • Autonomous agents themselves, self-reproducing systems carrying out one or more work cycles linking exergonic and endergonic processes in a cyclic fashion that propagate the union of catalysis, constraint construction, and process organization that constitute such autonomous agents are but the most miraculously diversifying examples of this universal process in our unfolding, ever-changing universe.
