Metabolic transcription analysis of engineered Escherichia coli strains that overproduce L-phenylalanine.

abstract：BACKGROUND:Prions were first identified as infectious proteins associated with fatal brain diseases in mammals. However, fungal prions behave as epigenetic regulators that can alter a range of cellular processes. These proteins propagate as self-perpetuating amyloid aggregates being an example of structural inheritance...
