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

flhDRegulator of flagellar biosynthesis; Functions in complex with FlhC as a master transcriptional regulator that regulates transcription of several flagellar and non- flagellar operons by binding to their promoter region. Activates expression of class 2 flagellar genes, including fliA, which is a flagellum-specific sigma factor that turns on the class 3 genes. Also regulates genes whose products function in a variety of physiological pathways (Probable); Belongs to the FlhD family. (116 aa)    
Predicted Functional Partners:
flhC
Regulator of flagellar biosynthesis; Functions in complex with FlhD as a master transcriptional regulator that regulates transcription of several flagellar and non- flagellar operons by binding to their promoter region. Activates expression of class 2 flagellar genes, including fliA, which is a flagellum-specific sigma factor that turns on the class 3 genes. Also regulates genes whose products function in a variety of physiological pathways (Probable); Belongs to the FlhC family.

ydiV
Putative diguanylate cyclase/phosphodiesterase domain 1; Acts as an anti-FlhC(2)FlhD(4) factor by binding to FlhD, decreasing its ability to bind DNA, and thus negatively regulates expression of flagellar class II operons, decreasing motility in nutrient-poor medium. Required for resistance to host phagocyte oxidase. Suppresses killing of macrophages, while promoting resistance to hydrogen peroxide. Data regarding c-di-GMP is controversial; suppresses bacterial c-di-GMP levels but neither synthesizes nor degrades c-di-GMP. Belongs to the YdiV family.

STM1697
Putative diguanylate cyclase/phosphodiesterase domain 2; Similar to E. coli orf, hypothetical protein (AAC74777.1); Blastp hit to AAC74777.1 (237 aa), 29% identity in aa 17 - 189.
    
 
 0.974
fliA
Sigma F (sigma 28) factor of RNA polymerase; 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. May regulate the expression of genes involved in virulence.
 
 
 0.972
motB
Enables flagellar motor rotation; MotA and MotB comprise the stator element of the flagellar motor complex. Required for the rotation of the flagellar motor. Might be a linker that fastens the torque-generating machinery to the cell wall (By similarity).
 
  
 0.963
fliC
Flagellar biosynthesis; Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella.
   
  
 0.942
fliD
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.
 
  
 0.937
fliL
Flagellar biosynthesis; Controls the rotational direction of flagella during chemotaxis; Belongs to the FliL family.
  
  
 0.933
flgM
anti-FliA factor; 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.
   
  
 0.911
flgA
Flagellar biosynthesis protein; Involved in the assembly process of the P-ring formation. It may associate with FlgF on the rod constituting a structure essential for the P-ring assembly or may act as a modulator protein for the P- ring assembly; Belongs to the FlgA family.
