Thiobacillus thioparus THI 115 : thiocyanate hydrolase Inferred from experiment : scnA , scnB , scnC

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 Inferred by computational analysis [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.
