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

trkIPotassium uptake transporter TrkI; Low-affinity potassium transport system. Interacts with Trk system potassium uptake protein TrkA; Belongs to the TrkH potassium transport family. (480 aa)    
Predicted Functional Partners:
trkA
Potassium uptake protein TrkA.
 
 
 0.986
kdpE
Two-component system, OmpR family, KDP operon response regulator KdpE; Two component signal transduction system controlling the osmosenstive K+ channel response regulator KdpE.
      
 0.871
rsmB
16S rRNA (cytosine967-C5)-methyltransferase RsmB; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
  
  
 0.797
fmt
methionyl-tRNA formyltransferase Fmt; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
  
  
 0.763
def
Peptide deformylase Def; Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions.
       0.710
exaC
NAD+-dependent acetaldehyde dehydrogenase ExaC; Belongs to the aldehyde dehydrogenase family.
      
 0.631
SO_0695
Potassium efflux protein CPA2 family; Belongs to the monovalent cation:proton antiporter 2 (CPA2) transporter (TC 2.A.37) family.
  
 
 0.595
SO_0033
Peptidoglycan-binding protein.
       0.521
ktrA
Sodium-dependent potassium uptake system NAD binding component KtrA.
  
 
 0.514
kvaP
Voltage-gated potassium uptake system KvaP.
  
 
 0.514
