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

lamBMaltose outer membrane porin (maltoporin); Involved in the transport of maltose and maltodextrins, indispensable for translocation of dextrins containing more than three glucosyl moieties. A hydrophobic path ('greasy slide') of aromatic residues serves to guide and select the sugars for transport through the channel. Also acts as a receptor for several bacteriophages including lambda. (446 aa)    
Predicted Functional Partners:
malE
Maltose transporter subunit; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Binds maltose and higher maltodextrins such as maltotriose. Belongs to the bacterial solute-binding protein 1 family.
 
  
 0.999
malK
Maltose ABC transportor ATPase; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Maltooligosaccharide importer (TC 3.A.1.1.1) family.
 
  
 0.999
malM
Maltose regulon periplasmic protein; Not yet known. Might function in the uptake of a still unidentified substrate; To S.typhimurium MalM.
 
  
 0.999
malF
Maltose transporter subunit; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Probably responsible for the translocation of the substrate across the membrane.
 
  
 0.998
malG
Maltose transporter subunit; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Probably responsible for the translocation of the substrate across the membrane.
 
  
 0.997
ompF
Outer membrane porin 1a (Ia;b;F); Forms pores that allow passive diffusion of small molecules across the outer membrane. (Microbial infection) A mixed OmpC-OmpF heterotrimer is the outer membrane receptor for toxin CdiA-EC536; polymorphisms in extracellular loops 4 and 5 of OmpC confer susceptibility to CdiA- EC536-mediated toxicity; Belongs to the Gram-negative porin family.
   
 
 0.993
ompC
Outer membrane porin protein C; Forms pores that allow passive diffusion of small molecules across the outer membrane. (Microbial infection) A mixed OmpC-OmpF heterotrimer is the outer membrane receptor for toxin CdiA-EC536; polymorphisms in extracellular loops 4 and 5 of OmpC confer susceptibility to CdiA- EC536-mediated toxicity; Belongs to the Gram-negative porin family.
     
 0.993
secA
Preprotein translocase subunit, ATPase; Required for protein export, interacts with the SecYEG preprotein conducting channel. SecA has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.
    
 
 0.988
tsx
Nucleoside channel, receptor of phage T6 and colicin K; Functions as substrate-specific channel for nucleosides and deoxynucleosides. Has a greater affinity for deoxynucleosides than for nucleosides, and does not transport free bases. In addition, constitutes the receptor for colicin K and phage T6. Belongs to the nucleoside-specific channel-forming outer membrane porin (Tsx) (TC 1.B.10) family.
   
 
 0.974
phoE
Outer membrane porin PhoE; Uptake of inorganic phosphate, phosphorylated compounds, and some other negatively charged solutes; Belongs to the Gram-negative porin family.
