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:
a 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.

lppBPutative methyl-accepting chemotaxis protein; Plays an important role in virulence. A highly abundant outer membrane lipoprotein that controls the distance between the inner and outer membranes. The only protein known to be covalently linked to the peptidoglycan network (PGN). Also non- covalently binds the PGN. The link between the cell outer membrane and PGN contributes to maintenance of the structural and functional integrity of the cell envelope, and maintains the correct distance between the PGN and the outer membrane (By similarity). (79 aa)    
Predicted Functional Partners:
lolA
Periplasmic protein; 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).

tonB
TonB; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates such as cobalamin, and various iron compounds (such as iron dicitrate, enterochelin, aerobactin, etc.). In the absence of TonB these receptors bind their substrates but do not carry out active transport. TonB also interacts with some colicins and is involved in the energy-dependent, irreversible steps of bacteriophages phi 80 and T1 infection. It could act to transduce energy from the cytoplasmic membrane to specific en [...]

lpp
Murein lipoprotein; Plays an important role in virulence. A highly abundant outer membrane lipoprotein that controls the distance between the inner and outer membranes. The only protein known to be covalently linked to the peptidoglycan network (PGN). Also non- covalently binds the PGN. The link between the cell outer membrane and PGN contributes to maintenance of the structural and functional integrity of the cell envelope, and maintains the correct distance between the PGN and the outer membrane (By similarity).

ycfU
Integral membrane protein ABC transporter; Similar to E. coli orf, hypothetical protein (AAC74200.1); Blastp hit to AAC74200.1 (399 aa), 93% identity in aa 1 - 399.
    
 
 0.705
STM3216
Similar to E. coli methyl-accepting chemotaxis protein I, serine sensor receptor (AAC77311.1); Blastp hit to AAC77311.1 (551 aa), 36% identity in aa 2 - 523.
      
 0.697
ycfW
Integral membrane protein ABC transporter; Similar to E. coli putative kinase (AAC74202.1); Blastp hit to AAC74202.1 (414 aa), 92% identity in aa 1 - 414.
    
 
 0.672
STM1254
Putative outer membrane lipoprotein.
   
  
 0.521
ycfV
ATP-binding protein ABC transporter; 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.
    
 
 0.510
ompA
Putative membrane component hydrogenase; With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm. Acts as a porin with low permeability that allows slow penetration of small solutes; an internal gate slows down solute passage.
  
 
 0.506
himA
Integration host factor (IHF), alpha subunit; This protein is one of the two subunits of integration host factor, a specific DNA-binding protein that functions in genetic recombination as well as in transcriptional and translational control.
