Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rickettsiales › Rickettsiaceae › Rickettsieae › Rickettsia › typhus group

Protein attributes

Sequence length	124 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Membrane-anchoring subunit of succinate dehydrogenase (SDH) By similarity.
Cofactor	Heme group. The heme is bound between the two transmembrane subunits By similarity.
Pathway	Carbohydrate metabolism; tricarboxylic acid cycle.
Subunit structure	Part of an enzyme complex containing four subunits: a flavoprotein, an iron-sulfur protein, plus two membrane-anchoring proteins, SdhC and SdhD. The complex can form homotrimers By similarity.
Subcellular location	Cell inner membrane; Multi-pass membrane protein.
Sequence similarities	Belongs to the cytochrome b560 family.
