text: Incidentally, the expression of ilvGMEDA operon suffers control (attenuation) by L-valine and/or L-isoleucine and/or L-leucine.
text: In connection with the production of L-valine, L-iso-leucine, α-ketoisovaleric acid, α-keto-β-methylvaleric acid or α-ketoisocaproic acid, preferably one or more of the genes or polynucleotides which code for enzymes of the biosynthesis of L-valine, L-isoleucine, α-ketoisovaleric acid, α-keto-β-methylvaleric acid or α-ketoisocaproic acid, selected from the group:
text: Since the expression of ilvGMEDA operon suffers control (attenuation) by L-valine and/or L-isoleucine and/or L-leucine, it is preferable that the region which is essential for attenuation is deleted or mutated to desensitize the repression of expression by produced L-valine.
