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
Your Input:
Gene Fusion
apaHBis(5'-nucleosyl)-tetraphosphatase (symmetrical); Hydrolyzes diadenosine 5',5'''-P1,P4-tetraphosphate to yield ADP (280 aa)    
Predicted Functional Partners:
annotation not available
Peptidyl-prolyl cis-trans isomerase (ppiase); Chaperone involved in the correct folding and assembly of outer membrane proteins, such as OmpA, OmpF and LamB. Recognizes specific patterns of aromatic residues and the orientation of their side chains, which are found more frequently in integral outer membrane proteins. May act in both early periplasmic and late outer membrane- associated steps of protein maturation. Essential for the survival of E.coli in stationary phase. Required for pilus biogenesis
16S rRNA m(6)A1518, m(6)A1519 dimethyltransferase, SAM-dependent; Specifically dimethylates two adjacent adenosines (A1518 and A1519) in the loop of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle. May play a critical role in biogenesis of 30S subunits. Has also a DNA glycosylase/AP lyase activity that removes C mispaired with oxidized T from DNA, and may play a role in protection of DNA against oxidative stress
4-hydroxy-L-threonine phosphate dehydrogenase, NAD-dependent; Catalyzes the NAD(P)-dependent oxidation of 4-(phosphooxy)-L- threonine (HTP) into 2-amino-3-oxo-4-(phosphooxy)butyric acid which spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate (AHAP)
Lps assembly om complex lptde, beta-barrel component; Together with LptE, is involved in the assembly of lipopolysaccharide (LPS) at the surface of the outer membrane. Contributes to n-hexane resistance
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis
Glutathione-regulated potassium-efflux system ancillary protein kefc; Pore-forming subunit of a potassium efflux system that confers protection against electrophiles. Catalyzes K(+)/H(+) antiport. Can also export rubidium, lithium and sodium
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) and other phosphoric acid esters . YigB is important for the formation of dormant persister cells
Fused trna nucleotidyltransferase/2',3'-cyclic phosphodiesterase/2' nucleotidase and phosphatase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows highest phosphatase activity in the presence of Ni(2+) and hydrolyzes pyrophosphate, canonical 5'-nucleoside tri- and diphosphates, NADP, and 2'-AMP with the production of Pi. Displays a metal-independen [...]
Membrane-anchored dnak co-chaperone, dna-binding protein; Regulatory DnaK co-chaperone. Direct interaction between DnaK and DjlA is needed for the induction of the wcaABCDE operon, involved in the synthesis of a colanic acid polysaccharide capsule, possibly through activation of the RcsB/RcsC phosphotransfer signaling pathway. The colanic acid capsule may help the bacterium survive conditions outside the host
