FunFam 203564: Chorismate mutase/prephenate dehydratase

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Chorismate mutase. [EC: 5.4.99.5]
Chorismate = prephenate.

    Prephenate dehydratase. [EC: 4.2.1.51]
    Prephenate = phenylpyruvate + H(2)O + CO(2).
    • This enzyme in the enteric bacteria also possesses EC 5.4.99.5 activity and converts chorismate into prephenate.

    3-demethylubiquinol 3-O-methyltransferase. [EC: 2.1.1.64]
    S-adenosyl-L-methionine + 3-demethylubiquinone-n = S-adenosyl-L- homocysteine + ubiquinone-n.
    • This enzyme is involved in ubiquinone biosynthesis.
    • Ubiquinones from different organisms have a different number of prenyl units (for example, ubiquinone-6 in Saccharomyces, ubiquinone- 9 in rat and ubiquinone-10 in human), and thus the natural substrate for the enzymes from different organisms has a different number of prenyl units.
    • However, the enzyme usually shows a low degree of specificity regarding the number of prenyl units.
    • For example, the human COQ3 enzyme can restore biosynthesis of ubiquinone-6 in coq3 deletion mutants of yeast.
    • The enzymes from yeast, Escherichia coli and rat also catalyze the methylation of 3,4-dihydroxy-5-all-trans-polyprenylbenzoate (a reaction that is classified as EC 2.1.1.114).

    Arabinonate dehydratase. [EC: 4.2.1.5]
    D-arabinonate = 2-dehydro-3-deoxy-D-arabinonate + H(2)O.
