MetaCyc Reaction: 1.1.1.57

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

EC Number: 1.1.1.57

Enzymes and Genes:

Escherichia coli K-12 substr. MG1655 : D-mannonate oxidoreductase Inferred from experiment : uxuB
Thermotoga maritima : D-mannonate dehydrogenase Inferred from experiment : uxuB

In Pathway: D-fructuronate degradation

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: fructuronate reductase

Enzyme Commission Synonyms: mannonate oxidoreductase, mannonic dehydrogenase, D-mannonate dehydrogenase, D-mannonate:NAD oxidoreductase

Standard Gibbs Free Energy (ΔrG in kcal/mol): 1.0817871 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Also reduces D-tagaturonate.
