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

Signal recognition particle (srp) component with 4.5s rna (ffs); Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Interaction with FtsY leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex [...]
One of at least 4 proteins (Era, RbfA, RimM and RsgA/YjeQ) that assist in the late assembly stage of the 30S ribosomal subunit. An accessory protein needed during the final step in assembly of the 30S ribosomal subunit, for assembly of the head region (the 16S rRNA 3' domain) It may act while Era is associated and before RimP in 30S subunit assembly . Interacts with S19 . Essential for efficient processing of 16S rRNA; a deletion mutant accumulates 17S rRNA . Deletions also do not assemble the head-associated ribosomal proteins correctly . May be needed both before and after RbfA durin [...]
Pyrimidine/purine-5'-nucleotide nucleosidase; Catalyzes the hydrolysis of the N-glycosidic bond of diverse pyrimidine and purine nucleotide 5'-monophosphates, to form ribose 5- phosphate and the corresponding free base. Can use AMP, GMP, IMP, CMP, dTMP and UMP as substrates. Cannot catalyze the reverse reactions. Is required for optimal growth in glucose minimal medium, possibly because it contributes to nucleoside pool homeostasis by degrading excess nucleotides and feeding back the ribose moiety to catabolism
Trna m(1)g37 methyltransferase, sam-dependent; Specifically methylates guanosine-37 in various tRNAs
Ftsz stabilizer, septal ring assembly factor, cell division stimulator; Non-essential, abundant cell division factor that is required for proper Z-ring formation. It is recruited early to the divisome by direct interaction with FtsZ, stimulating Z-ring assembly and thereby promoting cell division earlier in the cell cycle. Its recruitment to the Z-ring requires functional FtsA or ZipA
Pyrimidine deoxynucleotide diphosphatase nudi; Catalyzes the hydrolysis of nucleoside triphosphates, with a preference for pyrimidine deoxynucleoside triphosphates (dUTP, dTTP and dCTP)
L-tartrate:succinate antiporter; Catalyzes the uptake of tartrate in exchange for intracellular succinate. Essential for anaerobic L-tartrate fermentation
L(+)-tartrate dehydratase beta subunit; L-tartrate dehydratase, subunit B; Protein involved in fermentation
