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

tcyPSodium-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. (463 aa)    
Predicted Functional Partners:
mccB
Cystathionine gamma-lyase and homocysteine gamma-lyase for reverse transsulfuration pathway; Catalyzes the conversion of cystathionine to cysteine, and homocysteine to sulfide.
   
  
 0.878
yrrT
Putative AdoMet-dependent methyltransferase; Could be a S-adenosyl-L-methionine-dependent methyltransferase; Belongs to the methyltransferase superfamily. YrrT family.
   
  
 0.873
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.
   
  
 0.797
tcyA
Cystine ABC transporter (substrate-binding lipoprotein); Part of the ABC transporter complex TcyABC involved in L- cystine import.
   
  
 0.779
mccA
Cystathionine beta-synthase for the reverse transsulfuration pathway; Catalyzes the conversion of O-acetylserine and homocysteine to cystathionine.
   
  
 0.755
cysK
Cysteine synthase; Catalyzes the conversion of O-acetylserine to cysteine. Also acts as a sensor of cysteine availability in the signal transduction pathway modulating CymR activity. When cysteine is present, the pool of O-acetylserine (OAS) is low, which leads to the formation of a CymR- CysK complex and transcriptional repression of the CymR regulon occurs. In the absence of cysteine, the OAS pool is high and the CymR-CysK complex is mostly dissociated, leading to a faster dissociation of CymR from its DNA targets and the lifting of CymR-dependent repression.
   
  
 0.749
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.
   
    0.742
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).
   
  
 0.732
cysC
Adenylylsulfate kinase; Catalyzes the synthesis of activated sulfate; Belongs to the APS kinase family.
   
    0.729
ytlI
Transcriptional regulator (LysR family); Positively regulates the expression of ytmI operon in response to the availability of sulfur sources.
