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

ybfMPutative membrane phosphatase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme. (162 aa)    
Predicted Functional Partners:
psd
Phosphatidylserine decarboxylase; Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer); Belongs to the phosphatidylserine decarboxylase family. PSD-B subfamily. Prokaryotic type I sub-subfamily.
  
  
 0.949
pssA
Phosphatidylserine synthase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
  
    0.908
sigX
RNA polymerase ECF(extracytoplasmic function)-type sigma factor sigma(X); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. May be involved in the regulation of iron metabolism; Belongs to the sigma-70 factor family. ECF subfamily.
   
  
 0.689
pbpX
Penicillin-binding endopeptidase X; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the beta-lactamase family.
      
 0.688
ybfN
Hypothetical protein; Evidence 5: No homology to any previously reported sequences.
       0.605
ybfK
Carboxylesterase NP; Shows carboxylesterase activity in vitro.
  
    0.491
dltA
D-alanine:D-alanyl-carrier protein ligase; Catalyzes the first step in the D-alanylation of lipoteichoic acid (LTA), the activation of D-alanine and its transfer onto the D- alanyl carrier protein (Dcp) DltC. In an ATP-dependent two-step reaction, forms a high energy D-alanyl-AMP intermediate, followed by transfer of the D-alanyl residue as a thiol ester to the phosphopantheinyl prosthetic group of the Dcp. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram-positive bacteria, influencing the net charge of the cell wall. Belongs to the ATP [...]

ybfO
Putative exported hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
       0.416
spoVD
Penicillin-binding protein; Penicillin-binding protein with an unknown catalytic activity. May have a specialized role in the morphogenesis of spore cortex, which is a modified form of peptidoglycan. Pore cortex formation is determined primarily by the mother cell.
