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

Predicted Functional Partners:
Iron(iii) hydroxamate abc transporter membrane subunit; Part of the ABC transporter complex FhuCDB involved in iron(3+)-hydroxamate import. Responsible for the translocation of the substrate across the membrane
Fmn hydrolase / 5-amino-6-(5-phospho-d-ribitylamino)uracil phosphatase; Catalyzes the dephosphorylation of 5-amino-6-(5-phospho-D- ribitylamino)uracil, and thus could be involved in the riboflavin biosynthesis pathway . Is also able to dephosphorylate flavin mononucleotide (FMN), erythrose 4-phosphate and other phosphoric acid esters
Putative drug efflux mfs transporter, inner membrane protein; Inner membrane protein YbjJ; Putative DEOR-type transcriptional regulator
Hydrogen donor for nrdef electron transport system; Electron transport system for the ribonucleotide reductase system NrdEF
Part of the binding-protein-dependent transport system for ferric enterobactin. Probably responsible for energy coupling to the transport system
Outer-membrane receptor for ferric coprogen and ferric-rhodotorulic acid; Required for the uptake of Fe(3+) via coprogen, ferrioxamine B, and rhodotorulic acid
Two-component system, ompr family, torcad operon response regulator torr; Member of the two-component regulatory system TorS/TorR involved in the anaerobic utilization of trimethylamine-N-oxide (TMAO). Phosphorylated TorR activates the transcription of the torCAD operon by binding to four decameric boxes located in the torCAD promoter. Box1, 2 and 4 contain the DNA sequence 5'-CTGTTCATAT-3' and box3 contains the DNA sequence 5'-CCGTTCATCC-3'. Phosphorylated as well as unphosphorylated TorR negatively regulates its own expression by binding to box1 and 2
Component of sufbcd fe-s cluster assembly scaffold; The SufBCD complex acts synergistically with SufE to stimulate the cysteine desulfurase activity of SufS. The SufBCD complex contributes to the assembly or repair of oxygen-labile iron-sulfur clusters under oxidative stress. May facilitate iron uptake from extracellular iron chelators under iron limitation. Required for the stability of the FhuF protein
Tetr/acrr family transcriptional regulator, regulator of biofilm formation and stress response; Regulates the expression of a number of genes involved in biofilm formation and stress response. Target genes include six stress- response transcriptional regulators: csgD, which is a master regulator of biofilm formation, appY, sxy, ycgF, fimB and rcdA itself. This indicates that a large number of genes must be regulated indirectly via these transcriptional regulators. Acts by binding to the upstream region of its target genes
Enterobactin/ferrienterobactin esterase; Upon internalization, ferric enterobactin is processed via an exquisitely specific pathway that is dependent on FES activity, making iron available for metabolic use
