MetaCyc Reaction: 1.1.1.314

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions Composite Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 1.1.1.314

Enzymes and Genes:
sesquiterpene dehydrogenase ( Cichorium intybus )
germacrene A alcohol dehydrogenase/hydroxylase Inferred from experiment : GAO1 ( Barnadesia spinosa )
germacrene A alcohol dehydrogenase/hydroxylase Inferred from experiment : GAO1 ( Cichorium intybus )
germacrene A alcohol dehydrogenase/hydroxylase Inferred from experiment : GAO1 ( Lactuca sativa )
germacrene A oxidase : GAO ( Tanacetum parthenium )

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.
