Example sentences for: catalytically
How can you use “catalytically” in a sentence? Here are some example sentences to help you improve your vocabulary:
The middle histidine of the histidine triad (His96 in human Fhit), which is critical for hydrolysis of ApppA by Fhit [ 14 16 ] , is not necessary for tumor suppression [ 17 18 ] . Nonetheless, wild-type and His96Asn forms of Fhit are saturated by ApppA in the low micromolar range and form stable complexes with non-hydrolyzable ApppA in which two ApppA analogs are bound per Fhit dimer and all phosphates cluster on one surface of the protein [ 16 ] . These observations suggested that Fhit-substrate complexes may be the active, signaling form of Fhit and that the function of the catalytically essential histidine may be to terminate the lifetime of signaling complexes [ 16 ] .
In vitro studies have demonstrated that dephosphorylated cPLA 2 is catalytically active and that Ser 505phosphorylation increases activity by only ~30 percent [ 24 ] . In contrast, cells expressing the cPLA 2 S505A mutation fail to release AA in response to a low dose of calcium ionophore, but release similar amounts of AA as cells expressing wild-type cPLA 2 in response to high dose ionophore [ 22 ] . From these studies, it has been suggested that cPLA 2 Ser 505phosphorylation may have a role in regulating translocation [ 22 ] . A previous study demonstrated translocation of cPLA 2 S505A in response to Ca 2+ionophore, but did not address the kinetics of translocation, translocation in response to a physiological agonist, or differences in targeting [ 25 ] .
In addition, catalytically active Rec12 protein (or Rec12-dependent recombination) is required for faithful chromosome segregation during MII.
The figure also introduces two derivatives of the 'molecule' icon: a 'dimer' icon (adapted from Kohn [ 6]) to represent dimers such as cyclin D1-Cdk4 and a 'biomolecule' icon as a shorthand to represent catalytically active molecules with both 'concentration' and 'activity' properties (for example the kinases in the mitogen-to-ERK and -Akt kinase cascades).
Presence of catalytically inactive Rec12 protein enhances the fidelity of this distributive segregation system.
