Improved method for the biosynthesis of vitamin e

摘要

The invention relates to improved processes for the biosynthesis of vitamin E. These processes comprise inhibiting the breakdown of homogentisate via maleyl acetoacetate and fumaryl acetoacetate to give fumarate and acetoacetate. Also in accordance with the invention is the combination of this inhibition with processes which increase the supply of homogentisate, or which promote the conversion of homogentisate into vitamin E. According to the invention are nucleic acid constructs and vectors with which the processes according to the invention can be carried out, and transgenic plant organisms generated on the basis of this.
