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.

Score
prsAMolecular chaperone lipoprotein; Essential protein that plays a major role in protein secretion by helping the post-translocational extracellular folding of several secreted proteins. Has PPIase activity but it is not essential for its function in vivo; Belongs to the PrsA family. (292 aa)    
Predicted Functional Partners:
secDF
Protein-export membrane protein; Required for efficient translocation of secretory pre- proteins under conditions of hypersecretion but is not required for the release of mature proteins from the membrane. In the N-terminal section; belongs to the SecD/SecF family. SecD subfamily.
  
  
 0.865
htrB
HtrA-like serine protease; Degrades abnormal exported proteins and responsible for the propeptide processing of a natural pro-protein and for the maturation of a native protein. It also plays a prominent role in stress (heat shock, ethanol, puromycin and NaCl) resistance during active exponential growth (Probable); Belongs to the peptidase S1C family.
  
  
 0.793
htrA
Membrane bound serine protease Do, quality control protease (heat-shock protein); Degrades abnormal exported proteins and responsible for the propeptide processing of a natural pro-protein and for the maturation of a native protein. It also plays a prominent role in stress (heat shock, ethanol, puromycin and NaCl) resistance during active exponential growth (Probable); Belongs to the peptidase S1C family.
  
  
 0.792
cssS
Two-component sensor histidine kinase; Member of the two-component regulatory system CssS/CssR required to control the cellular response to secretion stress. Required for the transcription of htrA. Could detect misfolded proteins at the membrane-cell wall interface and then activate CssR by phosphorylation.
   
 
 0.764
secA
Translocase binding subunit (ATPase); Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
  
  
 0.757
cssR
Two-component response regulator; Member of the two-component regulatory system CssS/CssR required to control the cellular response to secretion stress.
   
  
 0.727
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.
 
 
 0.666
yxaL
Membrane associated protein kinase with beta-propeller domain; Increases the processivity of the PcrA helicase, but does not bind to DNA.
   
 
 0.647
amyE
Alpha-amylase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the glycosyl hydrolase 13 family.
   
  
 0.642
sscA
Spore assembly and germination protein; Spore protein involved in the assembly of several components of the spore coat, including CotB, CotG and CotH, and in spore germination.
     
 0.627
