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

PS3_13028Cysteine synthase; Belongs to the cysteine synthase/cystathionine beta- synthase family. (310 aa)    
Predicted Functional Partners:
metAA
Homoserine O-succinyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine; Belongs to the MetA family.
    
 0.961
PS3_13731
Cystathionine beta-lyase.
 
 0.960
PS3_17329
Cystathionine gamma-lyase.
 
 0.959
cysS
Cysteinyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 0.956
luxS
S-ribosylhomocysteine lyase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD). Belongs to the LuxS family.
  
 
 0.947
PS3_4931
O-acetylhomoserine (Thiol)-lyase.
 
 
 0.927
serC
Phosphoserine transaminase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine.
  
 
 0.925
PS3_11892
Aminopeptidase N.
    
 0.915
PS3_13004
Homocysteine S-methyltransferase.
     
 0.914
PS3_4009
Putative phosphopantothenate--cysteine ligase; Catalyzes two steps in the biosynthesis of coenzyme A. In the first step cysteine is conjugated to 4'-phosphopantothenate to form 4- phosphopantothenoylcysteine, in the latter compound is decarboxylated to form 4'-phosphopantotheine; In the C-terminal section; belongs to the PPC synthetase family.
