STRINGSTRING
STRING protein interaction network
Nodes:
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:
a 3D structure is known or predicted
Edges:
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
Others
textmining
co-expression
protein homology

ycgRFlagellar velocity braking protein, c-di-GMP-regulated; Acts as a flagellar brake, regulating swimming and swarming in a bis-(3'-5') cyclic diguanylic acid (c-di-GMP)-dependent manner. When bound to c-di-GMP it binds to elements of the flagellar motor (MotA and/or FliG and FliM , binding to FliM also occurs in the absence of c-di-GMP), causing the motor to slow down. Thus, increasing levels of c-di-GMP lead to decreased motility. Probably binds 1 c-di-GMP dimer per subunit. (244 aa)    
Predicted Functional Partners:
yhjH
cyclic-di-GMP phosphodiesterase, FlhDC-regulated; Involved in the control of the switch from cell motility to adhesion via regulation of cellular levels of cyclic-di-GMP (c-di-GMP). Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di-GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA and expression of the master biofilm regulator csgD. Effect on flagella is controlled via the c-di-GMP-b [...]

fliM
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.

fliG
Flagellar motor switching and energizing component; FliG 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.

yegE
Putative diguanylate cyclase; Catalyzes the synthesis of cyclic-di-GMP (c-di-GMP) via the condensation of 2 GTP molecules (By similarity). Involved in the control of the switch from cell motility to adhesion via regulation of cellular levels of c-di-GMP (Probable). Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di- GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA and expression of t [...]

yedQ
Putative membrane-anchored diguanylate cyclase; Catalyzes the synthesis of cyclic-di-GMP (c-di-GMP) via the condensation of 2 GTP molecules (By similarity). Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria. Involved in the regulation of cellulose production.
     
 0.972
motB
Protein that enables flagellar motor rotation; MotA and MotB comprise the stator element of the flagellar motor complex. Required for the rotation of the flagellar motor. Probably a linker that fastens the torque-generating machinery to the cell wall. Overexpression of this protein with MotA improves motility in a pdeH disruption, (a c-di-GMP phosphodiesterase) suggesting there is an interaction (direct or indirect) between the c-di-GMP-binding flagellar brake protein YcgR and the flagellar stator.
 
 
 0.937
fliD
Flagellar filament capping protein; Required for the morphogenesis and for the elongation of the flagellar filament by facilitating polymerization of the flagellin monomers at the tip of growing filament. Forms a capping structure, which prevents flagellin subunits (transported through the central channel of the flagellum) from leaking out without polymerization at the distal end; Belongs to the FliD family.
 
  
 0.921
fliA
RNA polymerase, sigma 28 (sigma F) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor controls the expression of flagella-related genes.
 
  
 0.912
fliS
Flagellar biosynthesis; repressor of class 3a and 3b operons (RflA activity); Protein involved in flagellum assembly and taxis.
 
  
 0.909
flgM
Anti-sigma factor for FliA (sigma 28); Responsible for the coupling of flagellin expression to flagellar assembly by preventing expression of the flagellin genes when a component of the middle class of proteins is defective. It negatively regulates flagellar genes by inhibiting the activity of FliA by directly binding to FliA; Belongs to the FlgM family.
