Abstract (en)

[origin: EP1074629A1] The invention relates to the field of providing additional nutritional value to a (micro-)organism by equipping a cell or cells of said organism with means for producing desired levels of an amino acid, preferably a so-called essential amino acid. The invention provides a method for regulating the flux, concentration or biosynthesis of a desired amino acid in a cell comprising providing said cell with a nucleic acid encoding a proteinaceous substance comprising at least said amino acid, such a proteinaceous substance herein also called sink protein whereby sink stands for the capacity of said proteinaceous substance to function as sink or reservoir for the desired amino acid, thereby regulating or reducing the amount or concentration of available of free amino acid in said cell by binding it through transcription and translation processes to the sink protein encoded by the additional nucleic acid.
