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.

nadE2NH(3)-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source. (576 aa)    
Predicted Functional Partners:
nadD
Conserved hypothetical protein; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
  
 
 0.992
NADK
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 specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP (By similarity).
 
  
 0.988
cobB
Regulatory protein, SIR2 family; NAD-dependent protein deacetylase which modulates the activities of several enzymes which are inactive in their acetylated form. Has also depropionylation activity in vitro. Also able to ADP- ribosylate peptide substrates with Arg or Lys in the +2 position. The role of this function in vivo is not clear.

TM_1217
Glutamate synthase, beta subunit; Similar to PID:2244618 percent identity: 58.52; identified by sequence similarity; putative.
  
 0.979
mazG
mazG protein; Catalyzes the hydrolysis of all eight canonical ribonucleoside triphosphates (NTP) and deoxyribonucleoside triphosphates (dNTP) to their corresponding nucleoside monophosphates ((d)NMP) and PPi and subsequently hydrolyzes the resultant PPi to Pi. The NTPase activity with deoxyribonucleoside triphosphates as substrate is higher than corresponding ribonucleoside triphosphates. dGTP is the best substrate among the deoxyribonucleoside triphosphates, and GTP is the best among the ribonucleoside triphosphates.

nadE1
NH(3)-dependent NAD(+) synthetase, putative; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
 
  
0.967
TM_1164
2-oxoacid ferredoxin oxidoreductase, alpha subunit; Similar to GB:AE000666 percent identity: 68.99; identified by sequence similarity; putative.
  
 
  0.902
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; Similar to GB:AE000657 percent identity: 61.39; identified by sequence similarity; putative.
     
 0.875
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
    
 0.849
purQ
Phosphoribosylformylglycinamidine synthase I; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist i [...]
