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:
some 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

yfiBPutative lipoprotein YfiB; Putative outer membrane protein (160 aa)    
Predicted Functional Partners:
yfiR
Repressor of the cell division arrest function of DgcN. Prevents DgcN relocation to the midcell
 
 
 0.997
yfiN
Bifunctional protein that catalyzes the synthesis of cyclic- di-GMP (c-di-GMP) in response to reductive stress and then dynamically relocates to the division site to arrest cell division in response to envelope stress. In the presence of high intracellular c-di-GMP levels, and in response to envelope stress, interacts with cell division proteins and halts cell division, without disassembling the Z ring, but by blocking its further progress toward cytokinesis . Part of a network that regulates cell motility by altering levels of c- di-GMP
 
  
 0.992
manY
The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane . The enzyme II ManXYZ PTS system is involved in mannose transport . Also functions as a receptor for bacterial chemotaxis and is required for infection of the cell by bacteriophage lambda where it most likely functions as a pore for penetration of lambda DNA (PubMed:4604906, PubMed:353494). ECO:0000269|PubMed:2999119, ECO:0000269|PubMed:353494,
      
 0.731
pal
Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity (PubMed:11115123, PubMed:17233825). The Tol-Pal system is also required for polar localization of chemoreceptors clusters .
  
   
 0.673
pfo
Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin
   
 
 0.648
ycgR
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.
      
 0.566
motB
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.
    
 
 0.526
yeaP
Catalyzes the synthesis of cyclic-di-GMP (c-di-GMP) via the condensation of 2 GTP molecules. Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria.
      
 0.513
csrD
Serves as a specificity factor required for RNase E-mediated decay of the small global regulatory RNAs CsrB and CsrC, it is probably not a nuclease. Nor does its activity involve c-di-GMP, despite its domain composition. Positively modulates motility gene expression, is also required for curli expression
