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

nadCNicotinate-nucleotide pyrophosphorylase; Identified by similarity to SP:P30011; match to protein family HMM PF01729; match to protein family HMM PF02749; match to protein family HMM TIGR00078; Belongs to the NadC/ModD family. (279 aa)    
Predicted Functional Partners:
nadA
Quinolinate synthetase complex, subunit A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.
 
 
 0.998
nadD
Nicotinate (nicotinamide) nucleotide adenylyltransferase; Identified by similarity to SP:P54455; match to protein family HMM PF01467; match to protein family HMM TIGR00125; Belongs to the NadD family.

 0.914
surE
Acid phosphatase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
  0.900
sdhA
Succinate dehydrogenase, flavoprotein subunit; Identified by similarity to SP:P31038; match to protein family HMM PF00890; match to protein family HMM PF01266; match to protein family HMM PF02910; match to protein family HMM TIGR01812; match to protein family HMM TIGR01816; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
    
 0.860
plsY
Putative membrane protein, TIGR00023; Catalyzes the transfer of an acyl group from acyl-phosphate (acyl-PO(4)) to glycerol-3-phosphate (G3P) to form lysophosphatidic acid (LPA). This enzyme utilizes acyl-phosphate as fatty acyl donor, but not acyl-CoA or acyl-ACP.
       0.636
ribD
Riboflavin biosynthesis protein RibD; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
     
 0.634
nnrE
YjeF family protein; Bifunctional enzyme that catalyzes the epimerization of the S- and R-forms of NAD(P)HX and the dehydration of the S-form of NAD(P)HX at the expense of ADP, which is converted to AMP. This allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. Catalyzes the epimerization of the S- and R-forms of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. This is a prerequisite for the S-specific NAD(P)H-hydrate dehydratase to allow the repair of both epim [...]
     
 0.606
ribE-2
6,7-dimethyl-8-ribityllumazine synthase; Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2- butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin.
  
  
 0.549
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
