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
Your Input:
Gene Fusion
pgaDPoly-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 (137 aa)    
Predicted Functional Partners:
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
Exports 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
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
Cellulose synthase, catalytic subunit; Catalytic subunit of cellulose synthase. It polymerizes uridine 5'-diphosphate glucose to cellulose, which is produced as an extracellular component for mechanical and chemical protection at the onset of the stationary phase, when the cells exhibit multicellular behavior (rdar morphotype). Coexpression of cellulose and thin aggregative fimbriae (curli fimbrae or fibers) leads to a hydrophobic network with tightly packed cells embedded in a highly inert matrix that confers cohesion, elasticity and tissue-like properties to colonies
C-di-gmp-binding protein bcse; Binds bis-(3'-5') cyclic diguanylic acid (c-di-GMP), the ability to bind c-di-GMP is important for its function
Blue light- and temperature-responsive anti-repressor; Binds to and releases the BluR repressor from its bound DNA target in a blue light-dependent (470 nm) fashion. A shift to low temperature also triggers a BluF-mediated relief of repression by BluR, suggesting BluF may serve as a thermometer. Blue light may act to increase the affinity of BluF for BluR, allowing it to be released from its operator. The protein has a reversible photocycle, and undergoes structural changes, probably in the EAL domain, in response to light
A probable inner membrane protein. Has been shown not to be a toxin, no effects on growth are seen in LB or minimal medium up to 6 or 21 hours (respectively) after induction of expression . Interacts with cytoskeletal proteins FtsZ and MreB; inhibits FtsZ GTP-dependent polymerization as well as MreB ATP- dependent polymerization . Restores production of prodigiosin antibiotic (Pig) in Serratia strains with deletions of sdhE-ygfX; overexpression of this protein and CptB also restores Pig production to a slightly lesser extent in Serratia
Regulator of cellulose synthase, cyclic di-gmp binding; Binds the cellulose synthase activator, bis-(3'-5') cyclic diguanylic acid (c-di-GMP)
Part of the binding-protein-dependent transport system AlsBAC for D-allose; probably responsible for the translocation of the substrate across the membrane
Uncharacterized protein YcdU; Pseudogene
