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

psdPhosphatidylserine decarboxylase; Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer). Only decarboxylates the lipid-linked form of the serine moiety, and not serine alone or derivatives like phosphoserine or glycerophosphoserine. (322 aa)    
Predicted Functional Partners:
pssA
Phosphatidylserine synthase; phospholipid synthesis; Protein involved in phospholipid biosynthetic process.
  
 0.992
aas
Fused 2-acylglycerophospho-ethanolamine acyl transferase/acyl-acyl carrier protein synthetase; Plays a role in lysophospholipid acylation. Transfers fatty acids to the 1-position via an enzyme-bound acyl-ACP intermediate in the presence of ATP and magnesium. Its physiological function is to regenerate phosphatidylethanolamine from 2-acyl-glycero-3- phosphoethanolamine (2-acyl-GPE) formed by transacylation reactions or degradation by phospholipase A1.
    
 0.945
pgsA
Phosphatidylglycerophosphate synthetase; This protein catalyzes the committed step to the synthesis of the acidic phospholipids; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
 
 
 
 0.936
pldA
Outer membrane phospholipase A; Has broad substrate specificity including hydrolysis of phosphatidylcholine with phospholipase A2 (EC 3.1.1.4) and phospholipase A1 (EC 3.1.1.32) activities. Strong expression leads to outer membrane breakdown and cell death; is dormant in normal growing cells. Required for efficient secretion of bacteriocins.
  
 
 0.926
cdsA
CDP-diglyceride synthetase; Protein involved in phospholipid biosynthetic process.
     
 0.918
mscM
Mechanosensitive channel protein, miniconductance; Mechanosensitive channel that protects cells against hypoosmotic stress when highly overexpressed. Gates spontaneously in response to increased membrane tension.
  
  
 0.885
pgpA
Phosphatidylglycerophosphatase A; Lipid phosphatase which dephosphorylates phosphatidylglycerophosphate (PGP) to phosphatidylglycerol (PG).
     
 0.865
clsA
Cardiolipin synthase 1; Catalyzes the reversible phosphatidyl group transfer from one phosphatidylglycerol molecule to another to form cardiolipin (CL) (diphosphatidylglycerol) and glycerol.
   
 
 0.840
plsB
Glycerol-3-phosphate O-acyltransferase; Catalyzes the transfer of an acyl group from acyl-ACP to glycerol-3-phosphate (G3P) to form lysophosphatidic acid (LPA). This enzyme can utilize either acyl-CoA or acyl-ACP as the fatty acyl donor. Belongs to the GPAT/DAPAT family.
   
  
 0.840
clsC
Stationary phase cardiolipin synthase 3; Catalyzes the synthesis of cardiolipin (CL) (diphosphatidylglycerol) from phosphatidylglycerol (PG) and phosphatidylethanolamine (PE).
   
 
 0.834
