Example sentences for: prephenate

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

  • It was preferable to use prephenate rather than L-arogenate as a substrate in the assay of *PheC activity, not only because the assay for L-arogenate dehydratase is tedious [ 17] but also because prephenate is much less expensive.

  • Nostoc has frnE (encoding a thiol-disulfide isomerase) inserted between tyrA (p) and aroB . Four subclasses of tyrA are defined according to the substrate specificities of the TyrA gene product: tyrA p , specific for prephenate; tyrA a , specific for arogenate; tyrA c , accepts either prephenate or arogenate; and tyrA (p) , has broad specificity but exhibits a distinct preference for prephenate.

  • As the prephenate dehydratase and prephenate dehydrogenase activities associated with the cytoplasmic AroQ•PheA and AroQ•TyrA proteins were not detected in this fraction, contamination with cytoplasmic species of AroQ was less than 1%.

  • Thus, Anabaena has two additional extra-operonic paralogs of aroA Iβ and trpD . In addition to extra-operonic, free-standing copies of trpAa and trpAb , a second fused gene ( trpAa • trpAb_2 ) encoding the two domains of anthranilate synthase is present in Anabaena . Nostoc has two extra-operonic copies of aroA Iβ , aroB and trpD . All cyanobacteria possess AroA of the Iβ class ( aroA Iβ ). While this is also true of the Anabaena/Nostoc lineage (in fact, having multiple copies), both Anabaena and Nostoc possess an additional gene encoding AroA of the Iα class ( aroA Iα ). All cyanobacteria possess a tyrA gene of the arogenate-specificity class ( tyrA a ), but the Anabaena/Nostoc supraoperons also possess a tyrA gene deemed to be a cyclohexadienyl dehydrogenase [ 28] with a favored specificity for prephenate ( tyrA (p) ) (C.A.B.

  • However, *PheC cannot be monitored as prephenate dehydratase in the presence of cytoplasmic P-protein because the PheA domain of that protein is prephenate dehydratase.
