STRINGSTRING
pssA protein (Escherichia coli K12 MG1655) - STRING interaction network
"pssA" - CDP-diacylglycerol--serine O-phosphatidyltransferase in Escherichia coli K12 MG1655
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

pssACDP-diacylglycerol--serine O-phosphatidyltransferase; Phosphatidylserine synthase; phospholipid synthesis; Protein involved in phospholipid biosynthetic process (451 aa)    
Predicted Functional Partners:
psd
Phosphatidylserine decarboxylase proenzyme; 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)
   
  0.982
pgsA
CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase; This protein catalyzes the committed step to the synthesis of the acidic phospholipids; Belongs to the CDP-alcohol phosphatidyltransferase class-I family (182 aa)
 
  0.979
cdsA
Phosphatidate cytidylyltransferase; CDP-diglyceride synthetase; Protein involved in phospholipid biosynthetic process (285 aa)
   
 
  0.950
cdh
CDP-diacylglycerol pyrophosphatase; Enzyme; Fatty acid and phosphatidic acid biosynthesis (251 aa)
         
  0.940
ynbB
Uncharacterized protein YnbB; Putative phosphatidate cytidiltransferase; Protein involved in nucleobase, nucleoside and nucleotide interconversion (298 aa)
         
  0.907
trpA
Tryptophan synthase alpha chain; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3- phosphate; Belongs to the TrpA family (268 aa)
   
 
    0.904
pldA
Phospholipase A1; 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 (289 aa)
         
  0.903
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF- independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism. Thus, is able to catalyze the cleavage of allothreonine and 3- phenylserine. Also catalyzes the irreversible conversion of 5,10 [...] (417 aa)
       
    0.901
trpB
Tryptophan synthase beta chain; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine; Belongs to the TrpB family (397 aa)
       
    0.900
serB
Phosphoserine phosphatase; Catalyzes the dephosphorylation of phosphoserine (P- Ser). Also catalyzes the hydrolysis of phosphothreonine (P-Thr) (322 aa)
       
    0.900
