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

yxeQPutative catabolic enzyme; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the PrpD family. (445 aa)    
Predicted Functional Partners:
yxeP
Putative amidohydrolase; Probably catalyzes the deacetylation of N-acetylcysteine (NAC) to acetate and cysteine. Is involved in a S-(2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine. Belongs to the peptidase M20 family.
  
    0.982
yxeL
Putative acetyltransferase; Catalyzes the N-acetylation of S-(2-succino)cysteine. Is involved in a S-(2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine. Moreover, 2SC is a toxic compound in B.subtilis at high exogenous concentrations, and this enzyme relieves 2SC toxicity via N-acetylation; Belongs to the acetyltransferase family.
 
    0.952
yxeO
Putative ABC transporter (ATP-binding protein); Probably part of the ABC transporter complex YxeMNO that could be involved in amino-acid import. May transport S-methylcysteine. Responsible for energy coupling to the transport system (Probable).
 
    0.939
yxeN
Putative ABC transporter (permease); Probably part of the ABC transporter complex YxeMNO that could be involved in amino-acid import. May transport S-methylcysteine. Probably responsible for the translocation of the substrate across the membrane (Probable); Belongs to the binding-protein-dependent transport system permease family.
  
    0.922
yxeM
Putative ABC transporter (binding lipoprotein); Probably part of the ABC transporter complex YxeMNO that could be involved in amino-acid import. May transport S-methylcysteine; Belongs to the bacterial solute-binding protein 3 family.
  
    0.909
yxeK
Putative monooxygenase; Probably catalyzes the oxygenation of the 2-position of the succinyl moiety of N-acetyl-S-(2-succino)cysteine, causing a spontaneous elimination reaction of the resulting hemithioketal that generates oxaloacetate and N-acetylcysteine (NAC). Is involved in a S- (2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine; Belongs to the NtaA/SnaA/SoxA(DszA) monooxygenase family.
 
    0.893
yxeR
Putative ethanolamine transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
  
    0.880
mmgF
2-methylisocitrate lyase; Involved in the methylcitric acid cycle. Catalyzes the cleavage of 2-methylisocitrate to yield pyruvate and succinate.
  
  
 0.696
tcyP
Sodium-cystine symporter; Mediates uptake of L-cystine, the oxidized form of L- cysteine. Although it is more specific for L-cystine, it could also transport a much broader range of amino acids and sulfur compounds including S-methylcysteine; Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family.
   
    0.668
citA
Citrate synthase I; Might regulate the synthesis and function of enzymes involved in later enzymatic steps of Krebs cycle. Loss in activity results in sporulation defect; Belongs to the citrate synthase family.
