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

ureIUrease accessory protein (ureI); Functions as a specific, H(+)-activated urea channel that increases the rate of urea entry into the cytoplasm, resulting in activation of cytoplasmic urease at acidic medium pH. Is essential for H.pylori gastric survival and colonization. Is necessary for the adaptation of urease activity to the extracellular pH, as in the presence of urea, UreI rapidly enhances the production of ammonia in the extracellular medium when the pH of the medium was decreased to pH5 or below. (195 aa)    
Predicted Functional Partners:
ureE
Urease accessory protein (ureE); Involved in urease metallocenter assembly. Binds nickel. Probably functions as a nickel donor during metallocenter assembly.
 
 
 0.996
ureF
Urease accessory protein (ureF); Required for maturation of urease via the functional incorporation of the urease nickel metallocenter.
 
  
 0.994
ureH
Urease accessory protein (ureH); Required for maturation of urease via the functional incorporation of the urease nickel metallocenter.
  
 
 0.990
ureG
Urease accessory protein (ureG); Facilitates the functional incorporation of the urease nickel metallocenter. This process requires GTP hydrolysis, probably effectuated by UreG.
  
 
 0.990
ureB
Urease beta subunit (urea amidohydrolase) (ureB); Ammonia produced by ureolysis increases the gastric pH thereby providing an environment permissive for colonization of the stomach; Belongs to the metallo-dependent hydrolases superfamily. Urease alpha subunit family.
  
 
 0.986
ureA
Urease alpha subunit (ureA) (urea amidohydrolase); Ammonia produced by ureolysis increases the gastric pH thereby providing an environment permissive for colonization of the stomach; In the N-terminal section; belongs to the urease gamma subunit family.
  
 
 0.964
glmM
Urease protein (ureC); Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate; Belongs to the phosphohexose mutase family.
    
 0.936
ppa
Inorganic pyrophosphatase (ppa); Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.
   
  
 0.750
atpA
ATP synthase F1, subunit alpha (atpA); Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit. Belongs to the ATPase alpha/beta chains family.
      
 0.744
trpC
Anthranilate isomerase (trpC); Bifunctional enzyme that catalyzes two sequential steps of tryptophan biosynthetic pathway. The first reaction is catalyzed by the isomerase, coded by the TrpF domain; the second reaction is catalyzed by the synthase, coded by the TrpC domain (By similarity).
