Thermotoga maritima : indole-3-glycerol phosphate synthase Inferred from experiment : trpC

In Pathway: L-tryptophan biosynthesis

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: indole-3-glycerol-phosphate synthase

Enzyme Commission Synonyms: indoleglycerol phosphate synθse, indoleglycerol phosphate synthase, indole-3-glycerophosphate synthase, 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose-5-phosphate carboxy-lyase (cyclizing)

Standard Gibbs Free Energy (ΔrG in kcal/mol): -34.453613 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
In some organisms, this enzyme is part of a multifunctional protein, together with one or more other components of the system for the biosynthesis of tryptophan [EC (anthranilate phosphoribosyltransferase), EC (anthranilate synthase), EC (tryptophan synthase) and EC (phosphoribosylanthranilate isomerase)].
