additional information
evolution
-
DAHP synthase belongs to a family of mononuclear iron-containing enzymes that are disabled by oxidative stress
evolution
-
despite significant sequence diversity, all known DAH7PS enzymes share a common (beta/alpha)8-barrel core and similar active site architectures formed by conserved residues that support a similar catalytic mechanism. On the basis of sequence and size, DAH7PS enzymes are classified into groups (type Ialpha, type Ibeta and type II). Each group features distinct structural elements appended to the core catalytic barrel that are associated with the allosteric inhibition of the enzymes and different quaternary structure associations. Neisseria meningitidis DAH7PS belongs to the type Ialpha group
metabolism
-

-

metabolism
the enzyme catalyzes the first step in shikimate pathway
metabolism

metabolism
-
first committed enzyme in the aromatic biosynthetic pathway of Escherichia coli, shikimate biosynthesis pathway overview
metabolism
first enzyme of the shikimate pathway in the biosynthesis of aromatic compounds which is responsible for primary carbohydrate metabolism with the biosynthesis of most aromatic amino acids
metabolism
-
first enzyme of the shikimate pathway that link the primary and specialized metabolism derived from aromatic amino acids. Isozyme AroG expression influences the levels of number of primary metabolites, such as shikimic acid and aromatic amino acids, as well as multiple volatile and non-volatile phenylpropanoids specialized metabolites and carotenoids
metabolism
-
3-deoxy-D-arabino-heptulosonate 7-phosphate synthase catalyses the first committed step of the shikimate pathway, which involves the aldol-like condensation of D-erythrose 4-phosphate and phosphoenolpyruvate to form 3-deoxy-D-arabino-heptulosonate 7-phosphate
metabolism
the enzyme catalyzes the first reaction in the shikimate pathway leading to the biosynthesis of aromatic metabolites including the aromatic acids L-Trp, L-Phe, and L-Tyr. As the entry point, feedback inhibition of DAH7PS by pathway end products is a key mechanism for the control of pathway flux

-
physiological function
-
expression of wild-type enzyme and phenylalanine-feedback insensitive mutant L175Q in Arabidopsis thaliana. Transgenic plants have comparable phenotypes and are fully fertile. The levels of shikimate, prephenate and Phe are higher in the different lines expressing the mutant enzyme than in the lines expressing the natural feedback-sensitive bacterial enzyme, and the control plants. Results imply that the bacterial enzyme is active in the transgenic plants and, similar to its operation in bacteria, the feedback insensitivity trait of the mutant enzyme is fundamental for enhancement of the flow of primary carbon metabolites via the shikimate pathway into the production of aromatic amino acids also in the plant
physiological function
-
the enzyme is involved in shikimate biosynthesis pathway
physiological function
allosteric regulation of the enzyme is mediated by L-Tyr binding to a discrete ACT regulatory domain appended to a core catalytic (beta/alpha)8 barrel
physiological function
-
3-deoxy-D-arabino-heptulosonate 7-phosphate synthase catalyses the aldol-like condensation of D-erythrose 4-phosphate and phosphoenolpyruvate to form 3-deoxy-D-arabino-heptulosonate 7-phosphate. Entry into the pathway is controlled by the allosteric regulation of enzyme DAH7PS by the pathway end products Phe, Tyr and Trp, or other intermediates of the pathway
additional information
-
allosteric response arising from changes in protein motion rather than conformation, and suggest ligands that modulate protein dynamics may be effective inhibitors of this enzyme. The nature of the extra barrel extensions is directly implicated in the sensitivity of the DAH7PS enzymes to allosteric control

additional information
-
isozyme AroG is not inhibited by L-Phe. In peroxide-stressed cells, the enzyme accumulates as an apoprotein, potentially with an oxidized cysteine residue. In superoxide-stressed cells, the enzyme acquires a nonactivating zinc ion in its active site, an apparent consequence of the repeated ejection of iron. Manganese supplementation protects the activity in both cases, which matches the ability of manganese to metallate the enzyme and to provide substantial oxidant-resistant activity. The damage to DAHP synthase can be completely restored in vivo, while in vitro, restoration is only partly, overview. Escherichia coli attempts to compensate for diminished DAHP synthase activity by increasing expression

additional information
-
binding structure determination and analysis, overview. The side chains of enzyme residues Lys188, Arg167 and Arg236 and the main chain peptide N of Ala166 that interact with the phosphate moiety of phosphoenolpyruvate form similar interactions with the phosphate or phosphonate functionalities of the three ligands, consistent with this portion of each inhibitor being able to mimic the phosphoenolpyruvate binding characteristics well. The tetrameric quaternary structures of enzyme NmeDAH7PS bound with (S)-phospholactate and vinyl phosphonate are identical to that of the isomorphous phosphoenolpyruvate-bound parent structure, PDB ID 4HSN. The increased inhibitor potency observed for the vinyl phosphonate over the (R)-phospholactate suggests that the active site is better prepared to accommodate a planar rather than tetrahedral intermediate
