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

mucDBelongs to the peptidase S1C family. (474 aa)    
Predicted Functional Partners:
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
  
 
 0.975
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
  
 
 0.973
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
  
  
 0.965
mucC
annotation not available
  
  
 0.964
algX
Plays two roles in the biosynthesis of the exopolysaccharide alginate: protects alginate from degradation as the polymer traverses the periplasm, and also plays a role in its O-acetylation. Acetylation of alginate causes the cells in the biofilm to adhere better to lung epithelium, form microcolonies, and resist the effects of the host immune system and/or antibiotics. Displays a low acetylesterase activity in vitro using a pseudosubstrate, 3-carboxyumbelliferyl acetate. Probably has acetyltransferase activity in vivo.
      
 0.954
algB
Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD
  
   
 0.888
rseP
Belongs to the peptidase M50B family
 
  
 0.856
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
      
 0.856
DR97_3834
MucE
      
 0.852
algR
Positive regulator of the algD gene, which codes for a GDP- mannose dehydrogenase, a key step enzyme in the alginate biosynthesis pathway
      
 0.750
