FunFam 192: Multifunctional tryptophan biosynthesis protein

There are 3 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
Indole-3-glycerol-phosphate synthase. [EC: 4.1.1.48]
1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate = 1-C- (3-indolyl)-glycerol 3-phosphate + CO(2) + H(2)O.
  • In some organisms, this enzyme is part of a multifunctional protein together with one or more components of the system for biosynthesis of tryptophan (EC 2.4.2.18, EC 4.1.3.27, EC 4.2.1.20 and EC 5.3.1.24).

Phosphoribosylanthranilate isomerase. [EC: 5.3.1.24]
N-(5-phospho-beta-D-ribosyl)anthranilate = 1-(2-carboxyphenylamino)-1- deoxy-D-ribulose 5-phosphate.
  • In some organisms, this enzyme is part of a multifunctional protein together with one or more components of the system for biosynthesis of tryptophan (EC 2.4.2.18, EC 4.1.1.48, EC 4.1.3.27 and EC 4.2.1.20).

Anthranilate synthase. [EC: 4.1.3.27]
Chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate.
  • In some organisms, this enzyme is part of a multifunctional protein together with one or more components of the system for biosynthesis of tryptophan (EC 2.4.2.18, EC 4.1.1.48, EC 4.2.1.20 and EC 5.3.1.24).
  • The native enzyme in the complex with uses either glutamine or (less efficiently) NH(3).
  • The enzyme separated from the complex uses NH(3) only.
