Enzymes and Genes:

Claviceps purpurea : agroclavine dehydrogenase Inferred from experiment : easG

In Pathway: ergotamine 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: agroclavine dehydrogenase

Enzyme Commission Synonyms: easG (gene name)

Standard Gibbs Free Energy (ΔrG in kcal/mol): 17.72351 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
The enzyme participates in the biosynthesis of ergotamine, an ergot alkaloid produced by some fungi of the Clavicipitaceae family. The reaction is catalysed in the opposite direction to that shown. The substrate for the enzyme is an iminium intermediate that is formed spontaneously from chanoclavine-I aldehyde in the presence of glutathione.
