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

mobAMolybdopterin-guanine dinucleotide synthase; Transfers a GMP moiety from GTP to Mo-molybdopterin (Mo-MPT) cofactor (Moco or molybdenum cofactor) to form Mo-molybdopterin guanine dinucleotide (Mo-MGD) cofactor. Is also involved in the biosynthesis of the bis-MGD form of the Moco cofactor (Mo-bisMGD) in which the metal is symmetrically ligated by the dithiolene groups of two MGD molecules. Is necessary and sufficient for the in vitro activation of the DMSOR molybdoenzyme that uses the Mo-bisMGD form of molybdenum cofactor, which implies formation and efficient insertion of the cofactor i [...] (194 aa)    
Predicted Functional Partners:
moeA
Molybdopterin molybdenumtransferase; Catalyzes the insertion of molybdate into adenylated molybdopterin with the concomitant release of AMP. Belongs to the MoeA family.
 0.999
mobB
Molybdopterin-guanine dinucleotide biosynthesis protein B; GTP-binding protein that is not required for the biosynthesis of Mo-molybdopterin guanine dinucleotide (Mo-MGD) cofactor, and not necessary for the formation of active molybdoenzymes using this form of molybdenum cofactor. May act as an adapter protein to achieve the efficient biosynthesis and utilization of MGD. Displays a weak intrinsic GTPase activity. Is also able to bind the nucleotides ATP, TTP and GDP, but with lower affinity than GTP.
 
 0.998
moaA
Molybdopterin biosynthesis protein A; Catalyzes, together with MoaC, the conversion of 5'-GTP to cyclic pyranopterin monophosphate (cPMP or molybdopterin precursor Z).
 
  
 0.964
mocA
CTP:molybdopterin cytidylyltransferase; Transfers a CMP moiety from CTP to Mo-molybdopterin (Mo-MPT) cofactor (Moco or molybdenum cofactor) to form Mo-molybdopterin cytosine dinucleotide (Mo-MCD) cofactor. Is specific for CTP; other nucleotides such as ATP and GTP cannot be utilized. Is also able to convert MPT to MCD in the absence of molybdate, however, with only one catalytic turnover.
    
 0.962
mog
Molybdochelatase incorporating molybdenum into molybdopterin; Catalyzes the adenylation of molybdopterin as part of the biosynthesis of the molybdenum-cofactor; Belongs to the MoaB/Mog family.
 
  
 0.941
moaC
Molybdopterin biosynthesis, protein C; Catalyzes the conversion of (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate to cyclic pyranopterin monophosphate (cPMP).
   
 0.928
narG
Nitrate reductase 1, alpha subunit; The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The alpha chain is the actual site of nitrate reduction.
   
 
 0.896
pfo
Pyruvate-flavodoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin.
  
  
 0.855
fnr
Oxygen-sensing anaerobic growth regulon transcriptional regulator FNR; Global transcription factor that controls the expression of over 100 target genes in response to anoxia. It facilitates the adaptation to anaerobic growth conditions by regulating the expression of gene products that are involved in anaerobic energy metabolism. When the terminal electron acceptor, O(2), is no longer available, it represses the synthesis of enzymes involved in aerobic respiration and increases the synthesis of enzymes required for anaerobic respiration.
     
 0.819
moaE
Molybdopterin synthase, large subunit; Converts molybdopterin precursor Z to molybdopterin. This requires the incorporation of two sulfur atoms into precursor Z to generate a dithiolene group. The sulfur is provided by MoaD.
