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
pgaBpoly-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 (672 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-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
Putative family 2 glycosyltransferase; Belongs to the glycosyltransferase 2 family
2'-O-acetyl-ADP-ribose deacetylase, regulator of RNase III activity; Deacetylates O-acetyl-ADP ribose to yield ADP-ribose and free acetate . Down-regulates ribonuclease 3 (RNase III) activity. Acts by interacting directly with the region of the ribonuclease that is required for dimerization/activation . Overexpression inhibits biofilm formation via an RNase III-independent pathway. This inhibition is RpoS-dependent . Overexpression also results in increased susceptibility to apramycin
Glucose-1-phosphate thymidylyltransferase; Catalyzes the formation of dTDP-glucose, from dTTP and glucose 1-phosphate, as well as its pyrophosphorolysis
Essential inner membrane duf3413 domain-containing protein; Inner membrane protein YejM; Putative sulfatase
Diacylglycerol kinase (atp); Recycling of diacylglycerol produced during the turnover of membrane phospholipid
CP4-57 prophage; DNA-binding transcriptional activator AlpA; Positive regulator of the expression of the slpA gene . When overexpressed, leads to suppression of the capsule overproduction and UV sensitivity phenotypes of cells mutant for the Lon ATP-dependent protease . Part of the cryptic P4-like prophage CP4-57 . Overexpression of AlpA leads to excision of the CP4-57 prophage by IntA. This inactivates ssrA (the gene upstream of the prophage) that encodes tmRNA which is required to rescue stalled ribosomes in a process known as trans- translation
Lipid a ethanolaminephosphotransferase; Catalyzes the addition of a phosphoethanolamine moiety to the lipid A. The phosphoethanolamine modification is required for resistance to polymyxin
