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.
