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

pgaAExports the biofilm adhesin polysaccharide poly-beta-1,6-N- acetyl-D-glucosamine (PGA) across the outer membrane. The PGA transported seems to be partially N-deacetylated since N-deacetylation of PGA by PgaB is needed for PGA export through the PgaA porin (807 aa)    
Predicted Functional Partners:
pgaC
Poly-n-acetyl-d-glucosamine synthase subunit pgac; Probable N-acetylglucosaminyltransferase that catalyzes the polymerization of single monomer units of UDP-N-acetylglucosamine to produce the linear homopolymer poly-beta-1,6-N-acetyl-D-glucosamine (PGA), a biofilm adhesin polysaccharide
 
  
 0.998
pgaD
Poly-n-acetyl-d-glucosamine synthase subunit pgad; Required for the synthesis of poly-beta-1,6-N-acetyl-D- glucosamine (PGA), a biofilm adhesin polysaccharide. May assist the glycosyltransferase PgaC in the polymerization of PGA
     
 0.985
pgaB
poly-beta-1,6-N-acetyl-D-glucosamine (PGA) N-deacetylase outer membrane export lipoprotein; Catalyzes the N-deacetylation of poly-beta-1,6-N-acetyl-D- glucosamine (PGA), a biofilm adhesin polysaccharide. N-deacetylation promotes PGA export through the PgaA porin

csrA
A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability, initially identified for its effects on central carbon metabolism . Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems . Binds to the 5'-UTR of mRNA to repress or activate translation; 2 binding sites on the homodimer can bridge 2 sites within target RNA (By similarity). Exerts reciprocal effects on enzymes of gluconeogenesis and glycogen biosynthesis versus [...]

ycdT
Diguanylate cyclase, membrane-anchored; Probably catalyzes the synthesis of cyclic-di-GMP (c-di-GMP) via the condensation of 2 GTP molecules. Overexpression leads to a strong repression of swimming; swimming returns to normal when residues 359-360 are both mutated to Ala. Overexpression also leads to a 20-fold increase in c-di-GMP levels in vivo. Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria

nhaR
Lysr family transcriptional regulator, transcriptional activator of nhaa; Plays a role in the positive regulation of NhaA
      
 0.822
dgcZ
Diguanylate cyclase, zinc-sensing; Catalyzes the synthesis of cyclic-di-GMP (c-di-GMP) via the condensation of 2 GTP molecules May act as a zinc sensor that controls, via c-di-GMP, post-translational events . Overexpression leads to a strong repression of swimming; swimming returnes to normal when residues 206-207 are both mutated to Ala. Overexpression also leads to a reduction in flagellar abundance and a 20-fold increase in c-di-GMP levels in vivo. Required for aminoglycoside-mediated induction of biofilm formation, it also plays a lesser role in biofilm production in response to ot [...]

evgS
Hybrid sensory histidine kinase in two-component regulatory system with evga; Member of the two-component regulatory system EvgS/EvgA. Phosphorylates EvgA via a four-step phosphorelay in response to environmental signals

cstA
Involved in peptide utilization during carbon starvation

glgC
Glucose-1-phosphate adenylyltransferase; Involved in the biosynthesis of ADP-glucose, a building block required for the elongation reactions to produce glycogen. Catalyzes the reaction between ATP and alpha-D-glucose 1-phosphate (G1P) to produce pyrophosphate and ADP-Glc
