FunFam 25: Histidine decarboxylase

There are 5 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
Aromatic-L-amino-acid decarboxylase. [EC: 4.1.1.28]
(1) L-dopa = dopamine + CO(2). (2) 5-hydroxy-L-tryptophan = 5-hydroxytryptamine + CO(2).
  • Also acts on other aromatic L-amino acids, including L-tryptophan.
  • Formerly EC 4.1.1.26 and EC 4.1.1.27.

Tyrosine decarboxylase. [EC: 4.1.1.25]
L-tyrosine = tyramine + CO(2).
  • The bacterial enzyme also acts on 3-hydroxytyrosine and, more slowly, on 3-hydroxyphenylalanine.

Histidine decarboxylase. [EC: 4.1.1.22]
L-histidine = histamine + CO(2).

    3,4-dihydroxyphenylacetaldehyde synthase. [EC: 4.1.1.107]
    L-dopa + O(2) + H(2)O = 3,4-dihydroxyphenylacetaldehyde + CO(2) + NH(3) + H(2)O(2).
    • The enzyme, isolated from the mosquito Aedes aegypti, catalyzes the production of 3,4-dihydroxylphenylacetaldehyde directly from L-dopa.
    • Dopamine is not formed as an intermediate (cf. EC 4.1.1.28).
    • The enzyme is specific for L-dopa and does not react with other aromatic amino acids with the exception of a low activity with alpha- methyl-L-dopa.

    L-tryptophan decarboxylase. [EC: 4.1.1.105]
    L-tryptophan = tryptamine + CO(2).
    • The enzyme has been characterized from bacteria, plants, and fungi.
    • Unlike EC 4.1.1.28 this enzyme is specific for L-typtophan.
