MetaCyc Reaction: 1.1.1.187

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

EC Number: 1.1.1.187

Enzymes and Genes:
GDP-4-keto-6-deoxy-D-mannose reductase Inferred from experiment : tld ( Aggregatibacter actinomycetemcomitans )

In Pathway: GDP-6-deoxy-D-talose 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: GDP-4-dehydro-D-rhamnose reductase

Enzyme Commission Synonyms: GDP-4-keto-6-deoxy-D-mannose reductase, GDP-4-keto-D-rhamnose reductase, guanosine diphosphate-4-keto-D-rhamnose reductase, GDP-6-deoxy-D-mannose:NAD(P)+ 4-oxidoreductase, GDP-6-deoxy-α-D-mannose:NAD(P)+ 4-oxidoreductase

Standard Gibbs Free Energy (ΔrG in kcal/mol): -10.649292 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
The enzyme, which operates in the opposite direction to that shown, forms a mixture of GDP-α-D-rhamnose and its C-4 epimer, GDP-6-deoxy-α-D-talose. cf. EC 1.1.1.281, GDP-4-dehydro-6-deoxy-D-mannose reductase and EC 1.1.1.135, GDP-6-deoxy-D-talose 4-dehydrogenase.
