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

tsrMethyl-accepting chemotaxis protein i, serine sensor receptor; Receptor for the attractant L-serine and related amino acids. Is also responsible for chemotaxis away from a wide range of repellents, including leucine, indole, and weak acids (551 aa)    
Predicted Functional Partners:
Chemotaxis regulator, protein-glutamate methyltransferase; Methylation of the membrane-bound methyl-accepting chemotaxis proteins (MCP) to form gamma-glutamyl methyl ester residues in MCP
Purine-binding chemotaxis protein chew; Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. It physically bridges CheA to the MCPs (methyl-accepting chemotaxis proteins) to allow regulated phosphotransfer to CheY and CheB
Two-component system, chemotaxis family, sensor kinase chea; Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. CheA is autophosphorylated; it can transfer its phosphate group to either CheB or CheY
Two-component system, chemotaxis family, protein-glutamate methylesterase/glutaminase; Involved in chemotaxis Part of a chemotaxis signal transduction system that modulates chemotaxis in response to various stimuli . Catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins or MCP) by CheR Also mediates the irreversible deamidation of specific glutamine residues to glutamic acid . Catalyzes its own deactivation by removing the activating phosphoryl group
Chemotaxis regulator transmitting signal to flagellar motor component; Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. In its active (phosphorylated or acetylated) form, CheY exhibits enhanced binding to a switch component, FliM, at the flagellar motor which induces a change from counterclockwise to clockwise flagellar rotation. Overexpression of CheY in association with MotA and MotB improves motility of a ycgR disruption, suggesting there is an interaction (direct or indirect) between the c-di-GMP-binding flagellar brake protein and th [...]
Chemotaxis regulator, protein phosphatase for chey; Plays an important role in bacterial chemotaxis signal transduction pathway by accelerating the dephosphorylation of phosphorylated CheY (CheY-P)
Two-component system, ompr family, aerobic respiration control sensor histidine kinase arcb; Member of the two-component regulatory system ArcB/ArcA. Sensor-regulator protein for anaerobic repression of the arc modulon. Activates ArcA via a four-step phosphorelay. ArcB can also dephosphorylate ArcA by a reverse phosphorelay involving His-717 and Asp-576
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
Flagellar motor switching and energizing component; FliM is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation
Flagellar hook-filament junction protein 1; Belongs to the flagella basal body rod proteins family
