Dickeya dadantii (strain 3937) (Erwinia chrysanthemi (strain 3937)) [Complete proteome] [HAMAP]

Taxonomic identifier

198628 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Dickeya

Protein attributes

Sequence length	207 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Required for disulfide bond formation in some periplasmic proteins such as PhoA or OmpA. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbA is reoxidized by DsbB. It is required for pilus biogenesis.
Subcellular location	Periplasm.
Sequence similarities	Belongs to the thioredoxin family. DsbA subfamily. Contains 1 thioredoxin domain.
