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:
some 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

phoHPhosphate starvation-inducible protein phoh and related proteins; Belongs to the PhoH family (354 aa)    
Predicted Functional Partners:
mazG
Nucleoside triphosphate pyrophosphohydrolase; Involved in the regulation of bacterial cell survival under conditions of nutritional stress. Regulates the type II MazE-MazF toxin-antitoxin (TA) system which mediates programmed cell death (PCD). This is achieved by lowering the cellular concentration of (p)ppGpp produced by RelA under amino acid starvation, thus protecting the cell from the toxicity of MazF. Reduction of (p)ppGpp can be achieved by direct degradation of (p)ppGpp or by degradation of NTPs, which are substrates for (p)ppGpp synthesis by RelA
 
  
 0.823
pstS
Phosphate abc transporter periplasmic binding protein; Part of the ABC transporter complex PstSACB involved in phosphate import
  
  
 0.795
phoB
Two-component system, ompr family, phosphate regulon response regulator phob; This protein is a positive regulator for the phosphate regulon. Transcription of this operon is positively regulated by PhoB and PhoR when phosphate is limited
  
   
 0.668
cobS
Adenosylcobinamide-gdp ribazoletransferase; Joins adenosylcobinamide-GDP and alpha-ribazole to generate adenosylcobalamin (Ado-cobalamin). Also synthesizes adenosylcobalamin 5'-phosphate from adenosylcobinamide-GDP and alpha-ribazole 5'- phosphate (By similarity)
      
 0.636
ghrA
Glyoxylate/hydroxypyruvate reductase a; Catalyzes the NADPH-dependent reduction of glyoxylate and hydroxypyruvate into glycolate and glycerate, respectively. Inactive towards 2-oxo-D-gluconate, 2-oxoglutarate, oxaloacetate and pyruvate. Only D- and L-glycerate are involved in the oxidative activity with NADP. Activity with NAD is very low
     
 0.619
gsiA
Glutathione abc transporter atp binding subunit gsia; Part of the ABC transporter complex GsiABCD involved in glutathione import. Responsible for energy coupling to the transport system
      
 0.608
psiE
Putative phosphate starvation-inducible protein; Belongs to the PsiE family
      
 0.608
rsfS
Ribosomal silencing factor rsfs; Functions as a ribosomal silencing factor. Addition to isolated ribosomal subunits partially inhibits their association, preventing translation. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8, preventing association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation
 
     0.596
garD
D-galactarate dehydrogenase; Catalyzes the dehydration of galactarate to form 5-dehydro-4- deoxy-D-glucarate
      
 0.580
phoA
Bacterial alkaline phosphatase; Belongs to the alkaline phosphatase family
      
 0.569
