Example sentences for: prephenate
How can you use “prephenate” in a sentence? Here are some example sentences to help you improve your vocabulary:
For routine assays with unpurified protein preparations, chorismate mutase and prephenate dehydratase were assayed spectrophotometrically by the method of Cotton and Gibson [ 38] as modified by Ahmad and Jensen [ 18], using 1 mM chorismate and 1 mM prephenate, respectively.
All the prephenate dehydratase activity in PAT1051 is derived from *PheC, which thus can be used as a convenient marker for the quality of the separation of the cellular compartments.
Before the recognition of their periplasmic location, it was known [ 31] that some organisms might have *AroQ but not *PheC ( Salmonella ) or *PheC but not *AroQ ( Klebsiella ). It was pointed out that appropriate mutants are better producers of prephenate in Salmonella than in Escherichia because of the presence of *AroQ in the former but not in the latter.
In the periplasmic system a mixture of flow routes (chorismate → prephenate → phenylpyruvate → phenylalanine or chorismate → prephenate → arogenate → phenylalanine) exist because of the ability of cyclohexadienyl dehydratase to accept either prephenate or arogenate and because of the ability of periplasmic aminotransferase (whose detailed characterization is not within the scope of this paper) to transaminate either phenylpyruvate or 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%.
