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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

lolELipoprotein release complex - inner membrane subunit; Part of an ATP-dependent transport system LolCDE responsible for the release of lipoproteins targeted to the outer membrane from the inner membrane. Such a release is dependent of the sorting-signal (absence of an Asp at position 2 of the mature lipoprotein) and of LolA (414 aa)    
Predicted Functional Partners:
lolD
Outer membrane-specific lipoprotein transporter subunit; Part of the ABC transporter complex LolCDE involved in the translocation of mature outer membrane-directed lipoproteins, from the inner membrane to the periplasmic chaperone, LolA. Responsible for the formation of the LolA-lipoprotein complex in an ATP-dependent manner. Such a release is dependent of the sorting-signal (absence of an Asp at position 2 of the mature lipoprotein) and of LolA

lolC
Lipoprotein release complex - inner membrane subunit; Part of an ATP-dependent transport system LolCDE responsible for the release of lipoproteins targeted to the outer membrane from the inner membrane. Such a release is dependent of the sorting-signal (absence of an Asp at position 2 of the mature lipoprotein) and of LolA
 
 
0.983
lolA
Participates in the translocation of lipoproteins from the inner membrane to the outer membrane. Only forms a complex with a lipoprotein if the residue after the N-terminal Cys is not an aspartate (The Asp acts as a targeting signal to indicate that the lipoprotein should stay in the inner membrane); the inner membrane retention signal functions at the release step
 
 
 0.978
lolB
Lipoprotein localization factor; Plays a critical role in the incorporation of lipoproteins in the outer membrane after they are released by the LolA protein. Essential for E.coli viability
  
 
 0.956
nagK
Catalyzes the phosphorylation of N-acetyl-D-glucosamine (GlcNAc) derived from cell-wall degradation, yielding GlcNAc-6-P. Has also low level glucokinase activity in vitro
 
    0.916
macB
Abc-type tripartite efflux pump atp binding/membrane subunit; Part of the tripartite efflux system MacAB-TolC. MacB is a non-canonical ABC transporter that contains transmembrane domains (TMD), which form a pore in the inner membrane, and an ATP-binding domain (NBD), which is responsible for energy generation. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, the system could also transport R-LPS or a similar glycolipid

pal
Peptidoglycan-associated outer membrane lipoprotein pal; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity The Tol-Pal system is also required for polar localization of chemoreceptors clusters
  
   0.833
bamA
Bamabcde complex om biogenesis outer membrane pore-forming assembly factor; 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 [...]

lnt
Apolipoprotein n-acyltransferase; Catalyzes the phospholipid dependent N-acylation of the N- terminal cysteine of apolipoprotein, the last step in lipoprotein maturation Utilizes a two-step reaction via a ping-pong mechanism . Lnt undergoes covalent modification in the presence of phospholipids, resulting in a thioester acyl-enzyme intermediate. It then transfers the acyl chain to the amine group of the N-terminal diacylglyceryl-modified cysteine of apolipoprotein, leading to the formation of mature triacylated lipoprotein . In vitro, can utilize the phospholipids phosphatidylethanolam [...]

lspA
Prolipoprotein signal peptidase (signal peptidase ii); This protein specifically catalyzes the removal of signal peptides from prolipoproteins
