Protein Domain : Sulfur oxidation c-type cytochrome SoxX IPR030999

Type	Family
Description	Members of this family are SoxX, a c-type cytochrome with a CxxCH motif, part of a heterodimer with SoxA. SoxAX cytochromes play a key role in bacterial thiosulfate oxidation [ , ].There are three distinct types of SoxAX proteins. Type I and II SoxAX proteins are heterodimers, while the heterotrimeric SoxAXK proteins form the third group. Type I SoxAX proteins have SoxA subunits with two heme groups and SoxX subunits with a molecular mass of approximately 14kDa, while the Type II SoxA proteins only contain one heme group, and are associated with SoxX proteins that have a molecular mass of approximately 20kDa. The increased molecular mass inthese SoxX proteins is largely due to the presence of an N-terminal extension [ ].
Short Name	Thiosulf_SoxX
