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

trkATrk system transport of potassium protein; Part of the constitutive potassium transport systems TrkG and TrkH. May regulate the transport activity of TrkG and TrkH systems. Binds to NAD(+) and NADH. In Salmonella it is required for resistance to antimicrobial peptides. (458 aa)    
Predicted Functional Partners:
trkH
Trk family potassium transport protein; Low-affinity potassium transport system. Interacts with Trk system potassium uptake protein TrkA and requires TrkE for transport activity (By similarity); Belongs to the TrkH potassium transport family.

fmt
10-formyltetrahydrofolate:L-methionyl-tRNA(fMet) N-formyltransferase; 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.

sun
Putative rRNA methylase; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
  
    0.914
kdpD
Sensory kinase in two-component regulatory system wtih KdpE; Regulates kdp operon (high-affinity potassium transport system); similar to E. coli sensor for high-affinity potassium transport system (AAC73789.1); Blastp hit to AAC73789.1 (894 aa), 89% identity in aa 1 - 894.
  
  
 0.721
ptsO
Phosphocarrier protein HPr-like NPr; Nitrogen related; exchanges phosphate with Enzyme I; similar to E. coli phosphocarrier protein HPr-like NPr, nitrogen related, exchanges phosphate with Enzyme I, Hpr (AAC76238.1); Blastp hit to AAC76238.1 (90 aa), 96% identity in aa 1 - 90.
      
 0.678
def
Peptide deformylase; 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.
  
    0.665
mscL
Mechanosensitive channel; Channel that opens in response to stretch forces in the membrane lipid bilayer. May participate in the regulation of osmotic pressure changes within the cell.
     
 0.652
kefC
CPA2 family K+ efflux antiporter, glutathione-regulated; Pore-forming subunit of a potassium efflux system that confers protection against electrophiles. Catalyzes K(+)/H(+) antiport.
     
 0.643
moaE
Molybdopterin converting factor, subunit 2; Converts molybdopterin precursor Z into molybdopterin. This requires the incorporation of two sulfur atoms into precursor Z to generate a dithiolene group. The sulfur is provided by MoaD (By similarity); Belongs to the MoaE family.
   
    0.577
nifJ
Similar to E. coli putative oxidoreductase, Fe-S subunit (AAC74460.1); Blastp hit to AAC74460.1 (1174 aa), 92% identity in aa 1 - 1174.
