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.

refZRegulator of FtsZ; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator. (207 aa)    
Predicted Functional Partners:
ezrA
Negative regulator of FtsZ ring formation; Negative regulator of FtsZ ring formation; modulates the frequency and position of FtsZ ring formation. Inhibits FtsZ ring formation at polar sites. Interacts either with FtsZ or with one of its binding partners to promote depolymerization.
     
 0.944
ftsZ
Cell-division initiation protein; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
   
 
 0.938
yshA
Conserved hypothetical protein; Activator of cell division through the inhibition of FtsZ GTPase activity, therefore promoting FtsZ assembly into bundles of protofilaments necessary for the formation of the division Z ring. It is recruited early at mid-cell but it is not essential for cell division (By similarity); Belongs to the ZapA family. Type 2 subfamily.
   
  
 0.804
ftsA
Cell-division protein essential fo Z-ring assembly; Cell division protein that is required for the assembly of the Z ring. May serve as a membrane anchor for the Z ring (By similarity). Binds and hydrolyzes ATP. Also involved in sporulation (Probable). Belongs to the FtsA/MreB family.
   
  
 0.791
sepF
Cell division machinery factor; Cell division protein that is part of the divisome complex and is recruited early to the Z-ring. Probably stimulates Z-ring formation, perhaps through the cross-linking of FtsZ protofilaments. Its function overlaps with FtsA; Belongs to the SepF family.
      
 0.742
minC
Cell-division regulator (septum placement); Cell division inhibitor that blocks the formation of polar Z ring septums. Rapidly oscillates between the poles of the cell to destabilize FtsZ filaments that have formed before they mature into polar Z rings. Prevents FtsZ polymerization. The MinCD complex plays an important role in asymmetric septum formation during sporulation of B.subtilis cells.
   
  
 0.729
divIVA
Cell-division initiation protein; May act as a pilot protein, directing MinCD to the polar septation sites or by inhibiting MinCD at the midcell site of division. Required for polar localization of the chromosome during sporulation.
      
 0.714
ytsP
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; Belongs to the free Met sulfoxide reductase family.
  
    0.702
ylbP
Putative acetyltransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
    0.639
racA
Chromosome-anchoring protein RacA; Required for the formation of axial filaments and for anchoring the origin regions at the cell poles in sporulating cells, thus ensuring proper chromosome segregation in the prespore. Binds in a dispersed manner throughout the chromosome but preferentially to sites clustered in the origin portion of the chromosome, causing condensation of the chromosome and its remodeling into an elongated, anchored structure; Belongs to the RacA family.
