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

otsBTrehalose-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). (266 aa)    
Predicted Functional Partners:
otsA
Trehalose-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. Belongs to the glycosyltransferase 20 family.
 
 0.999
treA
Periplasmic 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.
  
 0.990
treF
Cytoplasmic trehalase; Hydrolyzes trehalose to glucose. Could be involved, in cells returning to low osmolarity conditions, in the utilization of the accumulated cytoplasmic trehalose, which was synthesized in response to high osmolarity; Belongs to the glycosyl hydrolase 37 family.
  
 0.990
treC
trehalose-6-P 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; Belongs to the glycosyl hydrolase 13 family.
  
 0.968
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.
     
 0.925
crr
Glucose-specific enzyme IIA component of PTS; 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. The enzyme II complex composed of PtsG and Crr is involved in glucose transport. The non-phosphorylated EIII-Glc is an inhibitor for uptake of certain sugars such as maltose, melibiose, lactose, and glycerol. Phosphorylated EIII-Glc, however, may be an activator for adenylate cyclase. It is an im [...]

katE
Catalase HPII, heme d-containing; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide.
  
  
 0.897
talA
Transaldolase A; Transaldolase is important for the balance of metabolites in the pentose-phosphate pathway.
   
  
 0.873
ygaU
Uncharacterized protein; Highly specific potassium binding protein that is required for normal growth in the presence of high levels of external K(+). May act as a sensor of cytoplasmic K(+) concentration. Binds a single K(+) ion, which induces a large conformational change. Can also bind the larger alkali metal ions Rb(+) and Cs(+), and NH(4)(+). May be involved in the regulation of peptidoglycan cross-linking.
   
  
 0.831
fbaB
Fructose-bisphosphate aldolase class I; Protein involved in glycolysis; Belongs to the DeoC/FbaB aldolase family. FbaB subfamily.
