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.

pgtBProtein for signal transmission; Member of the two-component regulatory system PgtB/PgtA that regulates the inducible phosphoglycerate transport system. Activates PgtA by phosphorylation. (668 aa)    
Predicted Functional Partners:
pgtC
Protein for signal transmission; Required for PgtP expression, it may act jointly with the PgtA/PgtB signaling proteins.
 
 
 0.999
pgtA
Activator protein; Member of the two-component regulatory system PgtB/PgtA that regulates the inducible phosphoglycerate transport system. When activated by PgtB it acts in conjunction with sigma-54 as a transcriptional activator.
 
 
 0.998
pgtP
Transporter protein; The phosphoglycerate transporter protein is a part of the PGT transport system. It is the membrane bound transporter for phosphoglycerate into salmonella.
 
  
 0.887
yhgE
Putative inner membrane protein; Similar to E. coli putative transport (AAC76427.1); Blastp hit to AAC76427.1 (574 aa), 56% identity in aa 1 - 574.
   
  
 0.853
STM4261
Putative inner membrane protein; Fusion of two hypothetical proteins; (gi|7467255) and (gi|7467255).
      
 0.753
uhpB
Sensory histidine kinase in two-component regulatory sytem with UhpA; Part of the UhpABC signaling cascade that controls the expression of the hexose phosphate transporter UhpT. UhpB functions as a membrane-associated protein kinase that autophosphorylates in response to interaction with UhpC, and subsequently transfers its phosphate group to the response regulator UhpA. Can also dephosphorylate UhpA.
      
 0.719
uhpC
Regulator of uhpT expression; Part of the UhpABC signaling cascade that controls the expression of the hexose phosphate transporter UhpT. UhpC senses external glucose-6-phosphate and interacts with the histidine kinase UhpB, leading to the stimulation of the autokinase activity of UhpB. Belongs to the major facilitator superfamily. Organophosphate:Pi antiporter (OPA) (TC 2.A.1.4) family.
     
 0.688
nanM
Putative inner membrane protein; Converts alpha-N-acetylneuranimic acid (Neu5Ac) to the beta- anomer, accelerating the equilibrium between the alpha- and beta- anomers. Probably facilitates sialidase-negative bacteria to compete sucessfully for limited amounts of extracellular Neu5Ac, which is likely taken up in the beta-anomer. In addition, the rapid removal of sialic acid from solution might be advantageous to the bacterium to damp down host responses; Belongs to the NanM family.
  
    0.657
srfC
ssrAB activated gene; Predicted coiled-coil structure; SrfC (gi|8347260).
      
 0.592
cpdB
2',3'-cyclic-nucleotide 2'-phosphodiesterase; This bifunctional enzyme catalyzes two consecutive reactions during ribonucleic acid degradation. Converts a 2',3'-cyclic nucleotide to a 3'-nucleotide and then the 3'-nucleotide to the corresponding nucleoside and phosphate; Belongs to the 5'-nucleotidase family.
