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

modBCMolybdate ABC transporter permease protein. (598 aa)    
Predicted Functional Partners:
modA
Molybdenum ABC transporter periplasmic-binding protein.
 
 0.999
cysT
Sulfate ABC transporter permease protein CysT; Part of the ABC transporter complex (TC 3.A.1.6.1) involved in sulfate/thiosulfate import; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily.
 
  
0.853
nifH
Nitrogenase reductase NifH; The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein and the molybdenum-iron protein; Belongs to the NifH/BchL/ChlL family.
  
  
 0.843
cysW
Sulfate ABC transporter permease protein CysW.
 
  
0.840
bchL
Light-independent protochlorophyllide reductase iron-sulfur ATP-binding protein; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The L component serves as a unique electron donor to the NB-component of the complex, and binds Mg-ATP.
  
  
 0.802

Molybdenum-pterin binding protein.
  
  
 0.771
sbpA
Sulfate ABC transporter sulfate-binding protein.
  
  
 0.761
sbpA-2
Sulfate ABC transporter sulfate-binding protein.
  
  
 0.761
cysA
Sulfate transport system permease protein 1; Part of the ABC transporter complex CysAWTP involved in sulfate/thiosulfate import. Responsible for energy coupling to the transport system.
 
  
0.730
AFW94736.1
Putative phosphoadenosine phosphosulfate sulfurtransferase DndC.
