UniProt functional annotation for E3PPC4 | ||
|
|
|
|
|
|
||
| UniProt code: E3PPC4. |
|
||
| Organism: | |
Escherichia coli O78:H11 (strain H10407 / ETEC). |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia. |
|
||
|
||
| Function: | |
Fimbriae (also called pili), polar filaments radiating from the surface of the bacterium to a length of 0.5-1.5 micrometers and numbering 100-300 per cell, enable bacteria to colonize the epithelium of specific host organs. |
|
||
| Subunit: | |
CFA/I fimbriae are rather rigid, thread-like filaments of 0.5- 1 micrometer, with an apparent axial hole, and a diameter of 7 nanometers. A single CFA/I fimbria consists of about 100 identical protein subunits. |
| Subcellular location: | |
Fimbrium. |
| Induction: | |
CFA/I fimbriae are only expressed in the presence of the positive regulator CfaD. |
| Similarity: | |
Belongs to the fimbrial CS1 protein family. {ECO:0000305}. |
