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

nadDPutative nicotinate-nucleotide adenyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD). (218 aa)    
Predicted Functional Partners:
LBA1529
Hypothetical protein.
  
 0.995
rsfS
Hypothetical protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.
 
  
 0.963
nadE
NAD-synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source; Belongs to the NAD synthetase family.
  
 
 0.945
nadC
Nicotinic acid phosphoribosyltransferase (NAPRTase); Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Belongs to the NAPRTase family.
 
 
 0.942
ppnk
Putative inorganic polyphosphate-ATP-NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, 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.
  
 
 0.941
LBA1531
GTP-binding protein; COG1161 Predicted GTPases.
  
    0.931
LBA0117
Putative transcriptional regulator; Family; Sir2.
   
 0.919
LBA1532
Hypothetical protein.
  
    0.913
LBA1526
Hypothetical protein.
  
    0.872
tmcAL
Hypothetical protein; Catalyzes the formation of N(4)-acetylcytidine (ac(4)C) at the wobble position of elongator tRNA(Met), using acetate and ATP as substrates. First activates an acetate ion to form acetyladenylate (Ac- AMP) and then transfers the acetyl group to tRNA to form ac(4)C34.
