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:
Pyruvate/proton symporter; Transports pyruvate with a high affinity and specificity. The process is driven by the proton motive force . Part of a nutrient-sensing regulatory network composed of the two-component regulatory systems BtsS/BtsR and YpdA/YpdB, and their respective target proteins, BtsT and YhjX
Putative outer membrane porin for beta-glucuronides porin protein; Enhances the activity of the UidB (GusB) glucuronide transporter, on its own however it has no transport activity. Glucuronide transport does not occur in strain K12 due to a variant at position 100 of the UidB (GusB, AC P0CE44, AC P0CE45) protein
annotation not available
Suppressor of ompf assembly mutants; Involved in the inhibition of assembly of mutant ompF proteins. In general, could be involved in the assembly of outer membrane proteins
Anaerobic fumarate reductase catalytic and nad/flavoprotein subunit; Two distinct, membrane-bound, FAD-containing enzymes are responsible for the catalysis of fumarate and succinate interconversion; the fumarate reductase is used in anaerobic growth, and the succinate dehydrogenase is used in aerobic growth
Essential cell division protein that activates septal peptidoglycan synthesis and constriction of the cell. Acts on both sides of the membrane, via interaction with FtsA in the cytoplasm and interaction with the FtsQBL complex in the periplasm. These interactions may induce a conformational switch in both FtsA and FtsQBL, leading to septal peptidoglycan synthesis by FtsI and associated synthases (Probable) . Required for full FtsI activity . Required for recruitment of AmiC to the septal ring
Putative fimbrial-like adhesin protein; Part of the yehABCD fimbrial operon. Could contribute to adhesion to various surfaces in specific environmental niches
Outer membrane protein assembly factor bamc; Part of the outer membrane protein assembly complex (Bam), which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Nonessential member of the complex that stabilizes the interaction between the essential proteins BamA and BamD. Efficient substrate folding and insertion into the outer membrane requires all 5 subunits A lateral gate may open between the first and last strands of the BamA beta-barrel that allows substrate to insert into the outer membrane; comparison of the structures of complete and nearly [...]
CP4-57 prophage; putative GTP-binding protein YfjP; To E.coli YkfA and YeeP
Inner membrane protein - inhibits the rcs signaling pathway; Putative membrane protein IgaA homolog; Putative dehydrogenase
