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

gppAGuanosine pentaphosphatase; Catalyzes the conversion of pppGpp to ppGpp. Guanosine pentaphosphate (pppGpp) is a cytoplasmic signaling molecule which together with ppGpp controls the 'stringent response', an adaptive process that allows bacteria to respond to amino acid starvation, resulting in the coordinated regulation of numerous cellular activities. (494 aa)    
Predicted Functional Partners:
relA
(p)ppGpp synthetase I (GTP pyrophosphokinase); In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp (By similarity).
 
 
 0.974
ppk
Polyphosphate kinase; Catalyzes the reversible transfer of the terminal phosphate of ATP to form a long-chain polyphosphate (polyP); Belongs to the polyphosphate kinase 1 (PPK1) family.
 
  
 0.935
ppx
Exopolyphosphatase; Degradation of inorganic polyphosphates (polyP). Releases orthophosphate processively from the ends of the polyP chain.
  
  
0.921
spoT
(p)ppGpp synthetase II; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the degradation of ppGpp into GDP. It may also be capable of catalyzing the synthesis of ppGpp (By similarity); Belongs to the RelA/SpoT family.
  
 
 0.912
rhlB
Putative ATP-dependent RNA helicase; DEAD-box RNA helicase involved in RNA degradation. Has RNA- dependent ATPase activity and unwinds double-stranded RNA. Belongs to the DEAD box helicase family. RhlB subfamily.
  
    0.568
ygdH
Orf, hypothetical protein; Catalyzes the hydrolysis of the N-glycosidic bond of diverse pyrimidine and purine nucleotide 5'-monophosphates, to form ribose 5- phosphate and the corresponding free base. Can use AMP, GMP, IMP, CMP, dTMP and UMP as substrates. Cannot catalyze the reverse reactions. May contribute to nucleoside pool homeostasis by degrading excess nucleotides and feeding back the ribose moiety to catabolism. Belongs to the LOG family.
   
  
 0.469
trxA
Thioredoxin 1; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions; Belongs to the thioredoxin family.
