  Chorismatase Mechanisms Reveal Fundamentally Different Types of Reaction in a Single Conserved Protein Fold

  摘要：

  Chorismatases are a class of chorismate-converting enzymes involved in the biosynthetic pathways of different natural products, many of them with interesting pharmaceutical characteristics. So far, three subfamilies of chorismatases are described that convert chorismate into different (dihydro-)benzoate derivatives (CH-FkbO, CH-Hyg5, and CH-XanB2). Until now, the detailed enzyme mechanism and the molecular basis for the different reaction products were unknown. Here we show that the CH-FkbO and CH-Hyg5 subfamilies share the same protein fold, but employ fundamentally different reaction mechanisms. While the FkbO reaction is a typical hydrolysis, the Hyg5 reaction proceeds intramolecularly, most likely via an arene oxide intermediate. Two nonconserved active site residues were identified that are responsible for the different reaction mechanisms in CH-FkbO and CH-Hyg5. Further, we propose an additional amino acid residue to be responsible for the discrimination of the CH-XanB2 subfamily, which catalyzes the formation of two different hydroxybenzoate regioisomers, likely in a single active site. A multiple sequence alignment shows that these three crucial amino acid positions are located in conserved motifs and can therefore be used to assign unknown chorismatases to the corresponding subfamily.

  The invention relates to a process for the biosynthetic production of 4-amino-4-deoxychorismate (ADC) performed fermentatively in vivo with a 4-amino-4-deoxychorismate synthase, preferably a PabAB bipartite protein (which may be a fusion protein), at an increased level of activity, thereby obtaining a broth comprising ADC and 4-amino-4-deoxyprephenate (ADP), that are recovered. The invention also relates to a further process of converting the ADP into p-aminophenylalanine. The invention, moreover relates to biosynthetic production of [3R,4R]-4-amino-3-hydroxycyclohexa-1,5-diene-1-carboxylic acid (3,4-CHA), by concerted action of such 4-amino-4-deoxychorismate synthase and of an enzyme capable of converting isochorismate into [5S,6S]-5,6 dihydroxycyclohexa-1,3-diene-1-carboxylic acid (2,3-CHD), preferably a phenazine biosynthesis protein PhzD, including recovery of 3,4-CHA. The invention also relates to expression vectors and host cells for use in any of such processes. The invention further relates to the use of 3,4-CHA as a catalytically active product, in particular as a chiral catalyst. And the invention finally relates to synthesis of oseltamivir phosphate from 3,4-CHA.

  In the production of genetically-modified, non-pathogenic organisms particularly an improved production and isolation of trans-dihydroxycyclohexadiene carboxylic acids and/or derivatives thereof, the synthesis of the transhydroxy cyclohexadiene carboxylic acids is performed in an enantiomer-pure form without detectable impurities with chorismate by cultivation of at least one genetically altered non-pathogenic organism which has an aromate embolism and has, in comparison with a corresponding, genetically not altered organism, an increased activity of the isochorismate synthase (EntC) and isochorismatase (EntB) and an activity of the 2,3 dihydroxybenzoate synthase (EntA) which is close to zero, or an increased activity of the isochorismatase (EntB) and a reduced activity of the isochorismate synthase (EntC) and an activity of the 2,3-dihydroxybenzoat-synthase (entA) of close to zero.
