EC Number: 188.8.131.52
In Pathway: thiocyanate degradation II
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: thiocyanate hydrolase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): 37.684002 [Latendresse13]
Enzyme Commission Summary:
This reaction is different from the one described by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB). The reaction is different in that the official EC reaction represents the ionic form of thiocyanate (NCS -), and thus requires an hydroxy group on the products side in order to balance it.
