STRINGSTRING
STRING protein interaction network
Nodes:
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:
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

surAChaperone SurA; 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 (428 aa)    
Predicted Functional Partners:
bamA
Outer membrane protein assembly factor BamA; Part of the outer membrane protein assembly complex (Bam), which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Constitutes, with BamD, the core component of the assembly machinery. 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 complete Bam complexes show there is cons [...]

bamB
Outer membrane protein assembly factor BamB; 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, which may orient the flexible periplasmic domain of BamA for interaction with other Bam components, chaperones and nascent outer membrane proteins. 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 [...]

lptD
LPS-assembly protein LptD; Together with LptE, is involved in the assembly of lipopolysaccharide (LPS) at the surface of the outer membrane. Contributes to n-hexane resistance
  
 0.993
rsmA
Ribosomal RNA small subunit methyltransferase A; 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
  
 0.972
skp
Chaperone protein Skp; Molecular chaperone that interacts specifically with outer membrane proteins, thus maintaining the solubility of early folding intermediates during passage through the periplasm. Required for the efficient release of OmpA from the inner membrane, the maintenance of its solubility in the periplasm, and, in association with lipopolysaccharide (LPS), for the efficient folding and insertion of OmpA into the outer membrane; Belongs to the Skp family
 
 
 0.970
apaH
Bis(5'-nucleosyl)-tetraphosphatase [symmetrical]; Hydrolyzes diadenosine 5',5'''-P1,P4-tetraphosphate to yield ADP; Belongs to the Ap4A hydrolase family
 
 
 0.964
bamD
Outer membrane protein assembly factor BamD; Part of the outer membrane protein assembly complex (Bam), which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Constitutes, with BamA, the core component of the assembly machinery. Probably involved in transient protein interactions. 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 [...]

pdxA
4-hydroxythreonine-4-phosphate dehydrogenase; Catalyzes the NAD(P)-dependent oxidation of 4- (phosphohydroxy)-L-threonine (HTP) into 2-amino-3-oxo-4- (phosphohydroxy)butyric acid which spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate (AHAP); Belongs to the PdxA family
  
 0.952
degP
Periplasmic serine endoprotease DegP; DegP acts as a chaperone at low temperatures but switches to a peptidase (heat shock protein) at higher temperatures. Degrades transiently denatured and unfolded or misfolded proteins which accumulate in the periplasm following heat shock or other stress conditions. DegP is efficient with Val-Xaa and Ile-Xaa peptide bonds, suggesting a preference for beta-branched side chain amino acids. Only unfolded proteins devoid of disulfide bonds appear capable of being cleaved, thereby preventing non-specific proteolysis of folded proteins. Its proteolytic a [...]
