Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (Q88IJ7_PSEPK | Q88IJ7)
molecular function
    GO:0050661    NADP binding    Interacting selectively and non-covalently with nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP+, or the reduced form, NADPH.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0004764    shikimate 3-dehydrogenase (NADP+) activity    Catalysis of the reaction: shikimate + NADP+ = 3-dehydroshikimate + NADPH + H+.
biological process
    GO:0009073    aromatic amino acid family biosynthetic process    The chemical reactions and pathways resulting in the formation of aromatic amino acid family, amino acids with aromatic ring (phenylalanine, tyrosine, tryptophan).
    GO:0008652    cellular amino acid biosynthetic process    The chemical reactions and pathways resulting in the formation of amino acids, organic acids containing one or more amino substituents.
    GO:0009423    chorismate biosynthetic process    The chemical reactions and pathways resulting in the formation of the unsymmetrical ether derived from phosphoenolpyruvate and 5-phosphoshikimic acid formed as an intermediate in the biosynthesis of aromatic amino acids and many other compounds.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0019632    shikimate metabolic process    The chemical reactions and pathways involving shikimate, (3R,4S,5R)--3,4,5-trihydroxycyclohex-1-ene-1-carboxylate, the anion of shikimic acid. It is an important intermediate in the biosynthesis of aromatic amino acids.
