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 adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD). (228 aa)    
Predicted Functional Partners:
nadE
NH3-dependent 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.
 
 
 0.971
DIP1858
Conserved hypothetical protein; 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.
 
 
 0.966
nadC
Similar to Mycobacterium tuberculosis nicotinate-nucleotide pyrophosphorylase [carboxylating] NadC or Rv1596 or MT1632 or MTCY336.08c SWALL:NADC_MYCTU (SWALL:O06594) (285 aa) fasta scores: E(): 2.1e-43, 51.09% id in 274 aa, and to Salmonella typhimurium nicotinate-nucleotide pyrophosphorylase [carboxylating] NadC or STM0145 SWALL:NADC_SALTY (SWALL:P30012) (296 aa) fasta scores: E(): 1.6e-34, 41.17% id in 272 aa; Belongs to the NadC/ModD family.
    
 0.959
rsfS
Conserved 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.
 
  
 0.949
DIP1457
Putative competence-damage related protein; Similar to Streptomyces coelicolor hypothetical 18.5 kDa protein Sc7C7.09 TR:O86814 (EMBL:AL031031) (181 aa) fasta scores: E(): 1.7e-13, 36.87% id in 160 aa, and to the C-terminal region of Streptococcus pneumoniae putative competence-damage protein CinA or Exp10 or SP1941 SW:CINA_STRPN (P54184) (418 aa) fasta scores: E(): 4.3e-15, 47.86% id in 117 aa.
 
 
 0.938
ppnK
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.
 
 
 0.935
DIP0725
Putative hydrolase; Similar to C-terminal region of Vibrio cholerae NADH pyrophosphatase NudC or VC0331 SW:NUDC_VIBCH (Q9KV27) (269 aa) fasta scores: E(): 2.3e-11, 32.75% id in 174 aa.
     
 0.902
obg
GTP1/OBG-family GTP-binding protein; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family.
 
  
 0.862
proA
Gamma-glutamyl phosphate reductase; Catalyzes the NADPH-dependent reduction of L-glutamate 5- phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate. Belongs to the gamma-glutamyl phosphate reductase family.
  
  
 0.841
DIP1773
Similar to Mycobacterium leprae possible phosphoglycerate mutase ML1452 TR:Q9CC00 (EMBL:AL583922) (224 aa) fasta scores: E(): 1.1e-34, 44.26% id in 244 aa, and to Mycobacterium tuberculosis hypothetical protein Rv2419c TR:P71724 (EMBL:Z81368) (223 aa) fasta scores: E(): 6.3e-34, 52.88% id in 191 aa.
