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

algRAlginate biosynthesis regulatory protein AlgR; Positive regulator of the algD gene, which codes for a GDP- mannose dehydrogenase, a key step enzyme in the alginate biosynthesis pathway. (248 aa)    
Predicted Functional Partners:
algZ
Alginate biosynthesis protein AlgZ/FimS; Product name confidence: Class 1 (Function experimentally demonstrated in P. aeruginosa).
 
 
 0.999
algU
Sigma factor AlgU; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor regulates genes such as algD, involved in alginate biosynthesis.
   
  
 0.958
mucA
Anti-sigma factor MucA; Negative regulator of the sigma factor AlgU. Plays a role in the differentiation of P.aeruginosa into the alginate-producing form. Inactivation of mucA causes a switch from the non-mucoid to mucoid state resulting in constitutive expression of alginate biosynthetic genes.
  
  
 0.931
algD
GDP-mannose 6-dehydrogenase AlgD; Catalyzes the oxidation of guanosine diphospho-D-mannose (GDP-D-mannose) to GDP-D-mannuronic acid, a precursor for alginate polymerization. The alginate layer causes a mucoid phenotype and provides a protective barrier against host immune defenses and antibiotics.
      
 0.894
pilG
Twitching motility protein PilG; Is involved in pilus biosynthesis and twitching motility. May act as a single-domain response regulator whose function may be to receive a certain environmental signal(s) and then transduce that signal to the pilus assembly machinery via specific protein-protein interactions.
  
  
 0.884
amrZ
Alginate and motility regulator Z; Functions as both a transcriptional activator and repressor of multiple genes encoding virulence factors as well as genes involved in environmental adaptation. Plays a role in alginate production via the activation of AlgD which is the first gene in the alginate biosynthetic operon. Regulates also the transcription of genes responsible for type IV pili localization and twitching motility. Mediates transition of P.aeruginosa biofilm infections from colonizing to chronic biofilms through repression of the psl operon. Represses also its own transcription [...]

mucB
Negative regulator for alginate biosynthesis MucB; Negative regulator of the sigma factor AlgU. Plays a role in the differentiation of P.aeruginosa into the alginate-producing form. Inactivation of mucB causes conversion to mucoidy.
  
  
 0.869
algQ
Alginate regulatory protein AlgQ; The promoter for a critical alginate biosynthetic gene, AlgD, encoding GDP-mannose dehydrogenase, is activated only under conditions reminiscent of the cystic fibrosis lung (i.e. under high osmolarity), and at least two regulatory genes, AlgP and AlgQ, have been implicated in this activation process.
  
  
 0.866
vfr
Transcriptional regulator Vfr; Can bind cyclic AMP. Is a global regulator of virulence factor expression and is required for exotoxin A and protease production.
  
  
 0.860
algC
Phosphomannomutase AlgC; Highly reversible phosphoryltransferase. The phosphomannomutase activity produces a precursor for alginate polymerization, the alginate layer causes a mucoid phenotype and provides a protective barrier against host immune defenses and antibiotics. Also involved in core lipopolysaccaride (LPS) biosynthesis due to its phosphoglucomutase activity. Essential for rhamnolipid production, an exoproduct correlated with pathogenicity. Required for biofilm production. The reaction proceeds via 2 processive phosphoryl transferase reactions; first from enzyme-phospho-Ser-1 [...]
