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

Score
CysKCysteine synthase A; Belongs to the cysteine synthase/cystathionine beta- synthase family. (322 aa)    
Predicted Functional Partners:
CysE
Serine O-acetyltransferase.
 
 0.998
TW91_1291
Cystathionine beta-lyase.
  
 0.962
serC
Phosphoserine transaminase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
  
 
 0.931
TW91_0918
Aspartate aminotransferase.
   
 0.911
LuxS
S-ribosylhomocysteinase LuxS; 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.
  
 
 0.885
msrA
Peptide methionine sulfoxide reductase MsrA/msrB; Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine.
  
 
 0.861
metE
5-methyltetrahydropteroyltriglutamate-- homocysteine S-methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.
   
 
 0.860
PepN
Membrane alanyl aminopeptidase.
   
 0.839
pepA
Leucyl aminopeptidase; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides.
    
 0.828
CoaBC
Phosphopantothenoylcysteine decarboxylase/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.
