MetaCyc Reaction: 1.8.2.3

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions Protein-Modification Reactions
Reactions Classified By Substrate Macromolecule Reactions Protein-Reactions Protein-Modification Reactions

EC Number: 1.8.2.3

Enzymes and Genes:

Allochromatium vinosum : flavocytochrome c sulfide dehydrogenase Inferred from experiment : fccA , fccB
Paracoccus pantotrophus : SoxF Inferred from experiment : soxF
Thiobacillus sp. W5 : flavocytochrome c sulfide dehydrogenase Inferred from experiment

In Pathway: sulfide oxidation II (sulfide dehydrogenase)

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: sulfide-cytochrome-c reductase (flavocytochrome c)

Standard Gibbs Free Energy (ΔrG in kcal/mol): -6.126465 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
The enzyme from Allochromatium vinosum contains covalently bound FAD and covalently-bound c-type hemes.
