STRING protein interaction network
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 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
protein homology

Predicted Functional Partners:
Sigma-e factor negative regulatory protein rseb; 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
Sigma-e factor negative regulatory protein rsea; 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
Rna polymerase sigma-70 factor, ecf subfamily; 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
Peptidase do family protein; Belongs to the peptidase S1C family
annotation not available
Gdp-mannose 6-dehydrogenase; 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
Alginate biosynthesis transcriptional regulatory protein 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
Hypothetical protein; MucE
Na+-translocating ferredoxin:nad+ oxidoreductase subunit c; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane
Two-component system, lyttr family, response regulator algr; Positive regulator of the algD gene, which codes for a GDP- mannose dehydrogenase, a key step enzyme in the alginate biosynthesis pathway
