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

otsATrehalose 6-phosphate synthase; Catalyzes the transfer of glucose from UDP-alpha-D-glucose (UDP-Glc) to D-glucose 6-phosphate (Glc-6-P) to form trehalose-6- phosphate. Acts with retention of the anomeric configuration of the UDP-sugar donor. Essential for viability of the cells at low temperatures and at elevated osmotic strength (474 aa)    
Predicted Functional Partners:
otsB
trehalose-6-phosphate phosphatase, biosynthetic; Removes the phosphate from trehalose 6-phosphate (Tre6P) to produce free trehalose. Also catalyzes the dephosphorylation of glucose-6-phosphate (Glu6P) and 2-deoxyglucose-6-phosphate (2dGlu6P)
 
 0.999
treC
Trehalose-6-phosphate hydrolase; Hydrolyzes trehalose-6-phosphate to glucose and glucose 6- phosphate. Can also very effectively hydrolyzes p-nitrophenyl-alpha-D- glucopyranoside, but it does not recognize trehalose, sucrose, maltose, isomaltose, or maltodextrins
    
 0.982
galU
UTP--glucose-1-phosphate uridylyltransferase; May play a role in stationary phase survival
    
 0.951
glgC
Glucose-1-phosphate adenylyltransferase; Involved in the biosynthesis of ADP-glucose, a building block required for the elongation reactions to produce glycogen. Catalyzes the reaction between ATP and alpha-D-glucose 1-phosphate (G1P) to produce pyrophosphate and ADP-Glc
   
 
 0.948
treB
Trehalose-specific pts enzyme: iib and iic component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in trehalose transport at low osmolarity
     
 0.940
treA
Alpha,alpha-trehalase; Provides the cells with the ability to utilize trehalose at high osmolarity by splitting it into glucose molecules that can subsequently be taken up by the phosphotransferase-mediated uptake system
 
  
 0.919
katE
Catalase hpii, heme d-containing; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide
  
  
 0.918
osmY
Salt-inducible putative abc transporter periplasmic binding protein; Hyperosmotically inducible periplasmic protein; Protein involved in response to osmotic stress
  
  
 0.916
wcaN
UTP:glucose-1-phosphate uridylyltransferase, low activity; UTP--glucose-1-phosphate uridylyltransferase; Protein involved in nucleotide-sugar biosynthetic process
    
 0.910
bcsA
Cellulose synthase, catalytic subunit; Catalytic subunit of cellulose synthase. It polymerizes uridine 5'-diphosphate glucose to cellulose, which is produced as an extracellular component for mechanical and chemical protection at the onset of the stationary phase, when the cells exhibit multicellular behavior (rdar morphotype). Coexpression of cellulose and thin aggregative fimbriae (curli fimbrae or fibers) leads to a hydrophobic network with tightly packed cells embedded in a highly inert matrix that confers cohesion, elasticity and tissue-like properties to colonies
