Example sentences for: allosteric

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

  • The latter phenomenon is one whereby early-pathway regulatory mutations that increase intracellular chorismate concentrations result in exclusive metabolite flow toward L-phenylalanine because cyclohexadienyl dehydratase is insensitive to allosteric control.

  • This comparison is shown in Figure 5. Likewise, in those TrpEa proteins that lack a TrpEb_1 partner, instead being forced to function in concert with TrpEb_2, one might expect retention of catalytic residues but loss of allosteric residues.

  • In response to receptor activation, Syk becomes non-covalently associated with the BCR through tandem SH2 domains located in the amino terminal half of the protein [ 44 ] . Following engagement of the BCR, phosphorylation of specific tyrosine residues in immunoreceptor tyrosine-based activation motifs (ITAMs) found within the cytoplasmic tails of CD79a and CD79b provides docking sites for Syk localization [ 45 46 47 ] . The ability of phosphorylated ITAM peptides to selectively enhance Syk kinase activity in vitro suggests that recruitment of Syk to the receptor complex may serve to activate the kinase, in part, through allosteric changes in the structure of the Syk protein [ 44 48 49 ] . Upon activation, Syk and the receptor complex become localized in detergent-resistant cholesterol-rich membrane microdomains (lipid rafts), resulting in the segregation of the BCR complex from other membrane components [ 50 ] .

  • Although ACC was not regulated at the transcriptional level, cytoplasmic citrate (generated from the Acly reaction) is an allosteric activator of ACC, so less cytoplasmic citrate would lead to less activation of ACC [ 45 ] . Transcript levels of hepatic acetyl CoA synthetase 1 AMP forming (acetate:CoA ligase AMP forming; Acas1) were consistently down regulated by LC-PUFA (-2.

  • Overall, we conclude that binding of both the DNA and the RXR ligands can result in allosteric effects on the function of the CAR/RXR heterodimer.
