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.

nadENH(3)-dependent NAD+ synthetase (nadE); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source. (259 aa)    
Predicted Functional Partners:
MJ_0541
Conserved hypothetical protein; Similar to GP:1001812 percent identity: 32.62; identified by sequence similarity; putative; Belongs to the archaeal NMN adenylyltransferase family.
    
 0.962
MJ_0917
Conserved hypothetical protein; Involved in the regulation of the intracellular balance between NAD(H) and NADP(H), and is a key enzyme in the biosynthesis of NADP. Catalyzes the phosphorylation and dephosphorylation of NAD and NADP, respectively. Although it shows conflicting dual activities and is able to supply NADP, it seems that its physiological role is to prevent excess accumulation of NADP. Kinase can use ATP and other nucleoside triphosphates (UTP, TTP, CTP, GTP) as well as inorganic polyphosphate (poly(P)) as phosphoryl donors, however poly(P) is not considered to be the phys [...]

nadA
Quinolinate synthetase (nadA); Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.
  
  
 0.737
nadC
Nicotinate-nucleotide pyrophosphorylase (nadC); Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
     
 0.726
MJ_1521
Na+/H+ antiporter; This is probably a Na(+)/H(+) antiporter; Belongs to the monovalent cation:proton antiporter 1 (CPA1) transporter (TC 2.A.36) family.
       0.638
glnA
Glutamine synthetase (glnA); Probably involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. Beta-glutamate is a much poorer substrate than alpha-glutamate.
  
  
 0.628
nadX
Conserved hypothetical protein; Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate.
  
   
 0.564
MJ_1399
Alignment in; Identified by sequence similarity; putative; Belongs to the UPF0200 family.
     
 0.549
mdh
L-lactate dehydrogenase EGAD|7256|705; Catalyzes the reversible oxidation of (S)-malate and (S)- sulfolactate to oxaloacetate and sulfopyruvate, respectively. Can use both NADH and NADPH, although activity is higher with NADPH. Oxidation of (S)-sulfolactate is observed only in the presence of NADP(+). Can also oxidize tartrate. Cannot reduce pyruvate, nor alpha-ketoglutarate. Belongs to the LDH/MDH superfamily.
  
 
 0.518
MJ_0806
X-pro aminopeptidase (pepQ); Similar to SP:P46545 PID:1150454 PID:609078 percent identity: 33.33; identified by sequence similarity; putative.
