Taxonomic lineage

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

Protein attributes

Sequence length	105 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Component of the thioredoxin-thioredoxin reductase system. Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions By similarity.
Sequence similarities	Belongs to the thioredoxin family. Contains 1 thioredoxin domain.
Sequence caution	The sequence ABE04083.1 differs from that shown. Reason: Erroneous initiation.
