STRING protein interaction network
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

Gene Fusion
fluCP4-44 prophage; self recognizing antigen 43 (Ag43) autotransporter; Controls colony form variation and autoaggregation. May function as an adhesin (1039 aa)    
Predicted Functional Partners:
CP4-44 prophage; inner membrane protein YeeR; Inner membrane protein YeeR; Phage or Prophage Related
Involved in regulation of length and mediation of adhesion of type 1 fimbriae (but not necessary for the production of fimbriae). Adhesin responsible for the binding to D-mannose. It is laterally positioned at intervals in the structure of the type 1 fimbriae. In order to integrate FimH in the fimbriae FimF and FimG are needed
Putative autotransporter adhesin yfal; Probably an autotransporter
Lysr family transcriptional regulator, hydrogen peroxide-inducible genes activator; Hydrogen peroxide sensor. Activates the expression of a regulon of hydrogen peroxide-inducible genes such as katG, gor, ahpC, ahpF, oxyS (a regulatory RNA), dps, fur and grxA. OxyR expression is negatively autoregulated by binding to a 43 bp region upstream of its own coding sequence. OxyR is inactivated by reduction of its essential disulfide bond by the product of GrxA, itself positively regulated by OxyR. Has also a positive regulatory effect on the production of surface proteins that control the col [...]
Putative fimbrial adhesin protein sfmh; Part of the sfmACDHF fimbrial operon. Could contribute to adhesion to various surfaces in specific environmental niches. Increases adhesion to eukaryotic T24 bladder epithelial cells in the absence of fim genes
Cytoskeleton bundling-enhancing protein cbea and related proteins; Antitoxin component of a type IV toxin-antitoxin (TA) system . Antitoxin that counteracts the effect of its cognate toxin CbtA (YeeV) . It does not bind to the toxin but instead binds to MreB and FtsZ (the toxin targets), enhancing their polymerization by forming higher-order bundles; it is probably retained in the MreB and FtsZ filament bundles . The mechanism has been proposed to require intergenic DNA, in cis, between the cbeA (yeeU) and cbta (yeeV) genes . The intergenic region was not found to be necessary in anoth [...]
Uncharacterized protein YeeT; Phage or Prophage Related; Belongs to the YeeT/YkfH/YpjJ family
Curlin subunit, amyloid curli fibers, cryptic; Curlin is the structural subunit of the curli fimbriae. Curli are coiled surface structures that assemble preferentially at growth temperatures below 37 degrees Celsius. Curli can bind to fibronectin
Toxic component of a type IV toxin-antitoxin (TA) system Acts as a dual toxin inhibitor that blocks cell division and cell elongation in genetically separable interactions with FtsZ and MreB . Interacts with cytoskeletal proteins FtsZ and MreB; inhibits FtsZ GTP-dependent polymerization and GTPase activity as well as MreB ATP-dependent polymerization Binds to both the N- and C-terminus of FtsZ, likely blocking its polymerization and localization, leading to blockage of cell division . Overexpression results in inhibition of growth in liquid cultures and decrease in colony formation; th [...]
Putative secreted and surface-associated lipoprotein mucinase; Involved in a type II secretion system (T2SS, formerly general secretion pathway, GSP) for the export of folded proteins across the outer membrane
