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

psaAABC transporter substrate-binding protein - manganese transport; Part of an ATP-driven transport system; Belongs to the bacterial solute-binding protein 9 family. Lipoprotein receptor antigen (Lrai) subfamily. (309 aa)    
Predicted Functional Partners:
psaB
ABC transporter ATP-binding protein - manganese transport.
 
 
 0.999
psaC
ABC transporter membrane-spanning permease - manganese transport.
 
 0.999
ply
Pneumolysin (sulfhydryl-activated toxin that lyses cholesterol containing membranes); Sulfhydryl-activated toxin that causes cytolysis by forming pores in cholesterol containing host membranes. After binding to target membranes, the protein undergoes a major conformation change, leading to its insertion in the host membrane and formation of an oligomeric pore complex. Cholesterol may be required for binding to host membranes, membrane insertion and pore formation. Can be reversibly inactivated by oxidation (By similarity).

lytA
Autolysin (N-acetylmuramoyl-L-alanine amidase).
   
  
 0.949
ppmA
Proteinase maturation protein; Plays a major role in protein secretion by helping the post- translocational extracellular folding of several secreted proteins.
      
 0.941
adcB
ABC transporter membrane-spanning permease - Zinc (Zn2+) transport.
 
  
 0.927
flpA
Fibronectin-binding protein-like protein A; Part of the ribosome quality control system (RQC). Recruits Ala-charged tRNA and directs the elongation of stalled nascent chains on 50S ribosomal subunits, leading to non-templated C-terminal Ala extensions (Ala tail). The Ala tail promotes nascent chain degradation. May add between 1 and at least 8 Ala residues. Binds to stalled 50S ribosomal subunits.
      
 0.925
prtA
Cell wall-associated serine proteinase precursor PrtA.
   
  
 0.911
pspA
Surface protein pspA precursor.
   
  
 0.910
pspC
Choline binding protein A.
