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

MMP0146Conserved hypothetical protein. (468 aa)    
Predicted Functional Partners:
nifH-2
NifH/frxC family:ATP/GTP-binding site motif A (P-loop); 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.
  
  
 0.795
hpt
Hypoxanthine (guanine) phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
  
  
 0.777
hpcE
5-oxopent-3-ene-1,2,5-tricarboxylate decarboxylase.
  
    0.741
MMP0142
Thiamine pyrophosphate dependent enzyme related to acetolactate synthase; Citation: Bowen T.L. et al, Gene 188, 77 (1997); Belongs to the TPP enzyme family.
  
  
 0.630
MMP0143
Conserved hypothetical protein.
  
    0.609
MMP0015
Conserved hypothetical protein.
  
    0.608
acsA
acetyl-CoA synthetase, AMP-forming; Citation: J Bact 173:6383.
  
  
 0.547
MMP1677
4-hydroxybenzoate octaprenyl transferase related protein; Prenyltransferase that catalyzes the transfer of the geranylgeranyl moiety of geranylgeranyl diphosphate (GGPP) to the C2 hydroxyl of (S)-3-O-geranylgeranylglyceryl phosphate (GGGP). This reaction is the second ether-bond-formation step in the biosynthesis of archaeal membrane lipids.
 
  
 0.541
MMP0141
Conserved archaeal protein; Probable Zn finger protein; Prokaryotic DNA topoisomerase I-related (C-term).
  
    0.524
MMP0388
Geranylgeranyl bacterial chlorophyll reductase related; Is involved in the reduction of 2,3- digeranylgeranylglycerophospholipids (unsaturated archaeols) into 2,3- diphytanylglycerophospholipids (saturated archaeols) in the biosynthesis of archaeal membrane lipids. Catalyzes the formation of archaetidic acid (2,3-di-O-phytanyl-sn-glyceryl phosphate) from 2,3-di- O-geranylgeranylglyceryl phosphate (DGGGP) via the hydrogenation of each double bond of the isoprenoid chains.
