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

algQAlginate 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. (160 aa)    
Predicted Functional Partners:
rpoD
Sigma factor RpoD; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.
   
 
 0.989
algP
Alginate regulatory protein AlgP; 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.
  
  
 0.946
algH
Conserved hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences); Belongs to the UPF0301 (AlgH) family.
   
  
 0.886
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.
      
 0.881
algR
Alginate 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.
  
  
 0.866
rpoS
Sigma factor RpoS; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response.
  
 
 0.797
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate. The 12-kDa membrane-associated form synthesizes GTP in preference to other nucleoside triphosphates. Important for alginate synthesis; Belongs to the NDK family.

PA2178
Hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).
  
     0.753
PA1190
Conserved hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).
  
    0.749
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.
