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
gtrACPS-53 (KpLE1) prophage; putative bactoprenol-linked glucose translocase; Involved in O antigen modification. Involved in the translocation of bactoprenol-linked glucose across the cytoplasmic membrane (By similarity) (120 aa)    
Predicted Functional Partners:
CPS-53 (KpLE1) prophage; bactoprenol glucosyl transferase; Involved in O antigen modification. Catalyzes the transfer of the glucose residue from UDP-glucose to a lipid carrier (By similarity)
CPS-53 (KpLE1) prophage; serotype specific glucosyl transferase; Uncharacterized protein YfdI; Putative ligase
CPS-53 (KpLE1) prophage; prophage CPS-53 integrase; Integrase is necessary for integration of the phage into the host genome by site-specific recombination. In conjunction with excisionase, integrase is also necessary for excision of the prophage from the host genome
Formate-nitrite transporter family protein; Inner membrane protein YfdC; Putative transport protein
Lipid iva 4-amino-4-deoxy-l-arabinosyltransferase; Catalyzes the transfer of the L-Ara4N moiety of the glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides
Putative fimbrial protein yfcv; Part of the yfcOPQRSUV fimbrial operon. Could contribute to adhesion to various surfaces in specific environmental niches. Increases adhesion to eukaryotic T24 bladder epithelial cells in the absence of fim genes
Antitoxin of the hica-hicb toxin-antitoxin system; Antitoxin component of a type II toxin-antitoxin (TA) system. Functions as an mRNA interferase antitoxin; overexpression prevents HicA-mediated cessation of cell growth and inhibition of cell proliferation
Chito-oligosaccharide deacetylase; ChbG is essential for growth on the acetylated chitooligosaccharides chitobiose and chitotriose but is dispensable for growth on cellobiose and chitosan dimer, the deacetylated form of chitobiose. Deacetylation of chitobiose-6-P and chitotriose-6-P is necessary for both the activation of the chb promoter by the regulatory protein ChbR and the hydrolysis of phosphorylated beta-glucosides by the phospho-beta-glucosidase ChbF. Catalyzes the removal of only one acetyl group from chitobiose-6-P to yield monoacetylchitobiose-6-P, the inducer of ChbR and the [...]
Small subunit ribosomal protein s14; Binds 16S rRNA, required for the assembly of 30S particles and may also be responsible for determining the conformation of the 16S rRNA at the A site
Uncharacterized protein StfP; Phage or Prophage Related; To E.coli YfdL and M.jannaschii MJ0347
