Recommended name:
Curli assembly protein csgC

Gene names

Name:	csgC
Ordered Locus Names:	b1043, JW1026

Organism

Escherichia coli (strain K12) [Complete proteome] [HAMAP]

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia

Protein attributesHide

Sequence length	110 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)Hide

Function	Plays a role in the extracellular assembly of csgA into thin aggregative fimbriae (Tafi) fibers. Assembly may also require csgE. Tafi are thought to be assembled via an extracellular nucleation-precipitation (ENP) pathway, and possibly also via an intracellular non-csgC-dependent pathway By similarity.
Subcellular location	Periplasm By similarity.
Sequence similarities	Belongs to the CsgC/AgfC family.
