In Pathway: fluoroacetate and fluorothreonine 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.

Direct generic reactions:
an aldehyde + NAD+ + H2O → a carboxylate + NADH + 2 H+ (

an aldehyde + NAD(P)+ + H2O = a carboxylate + NAD(P)H + 2 H+ (
