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
cynTCarbonic anhydrase 1; Reversible hydration of carbon dioxide. Carbon dioxide formed in the bicarbonate-dependent decomposition of cyanate by cyanase (CynS) diffuses out of the cell faster than it would be hydrated to bicarbonate, so the apparent function of this enzyme is to catalyze the hydration of carbon dioxide and thus prevent depletion of cellular bicarbonate (219 aa)    
Predicted Functional Partners:
Cyanate aminohydrolase; Catalyzes the reaction of cyanate with bicarbonate to produce ammonia and carbon dioxide
Mfs transporter, cp family, cyanate transporter; This protein is part of an active transport system that transports exogenous cyanate into E.coli cells
Lysr family transcriptional regulator, cyn operon transcriptional activator; Positively regulates the cynTSX operon, and negatively regulates its own transcription. Binds specifically to the cynR-cynTSX intergenic region
Carbonic anhydrase 2; Belongs to the beta-class carbonic anhydrase family
Stimulator of caid and caib enzyme activities; Overproduction of CaiE stimulates the activity of CaiB and CaiD
Bacterial transferase hexapeptide domain protein; Belongs to the gamma-class carbonic anhydrase family
Aerobic c4-dicarboxylate transporter daua; Responsible for the aerobic transport of succinate from the periplasm to the cytoplasm at acidic pH. Can transport other C4- dicarboxylic acids such as aspartate and fumarate. May also play a role in the regulation of C4-dicarboxylic acid metabolism at pH 7, via regulation of expression and/or activity of DctA. May act as a co- sensor of DcuS
Sodium:serine/threonine symporter; Involved in the import of serine and threonine into the cell, with the concomitant import of sodium (symport system)
Fused 5-methylaminomethyl-2-thiouridine-forming methyltransferase and fad-dependent demodification enzyme; Catalyzes the last two steps in the biosynthesis of 5- methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at the wobble position (U34) in tRNA. Catalyzes the FAD-dependent demodification of cmnm(5)s(2)U34 to nm(5)s(2)U34, followed by the transfer of a methyl group from S-adenosyl-L-methionine to nm(5)s(2)U34, to form mnm(5)s(2)U34
Lysr family transcriptional regulator, tdc operon transcriptional activator; Transcriptional activator for the tdcABCDE operon
