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
msmRTranscriptional regulator (LacI family); Represses the melibiose operon melREDCA in the absence of melibiose or raffinose. Binds to two binding sites at the promoter region of the operon. (344 aa)    
Predicted Functional Partners:
msmE
Multiple sugar-binding lipoprotein; Part of the ABC transporter complex MelEDC-MsmX involved in melibiose, raffinose and stachyose import. Binds melibiose, raffinose and stachyose.
 
    0.929
melA
alpha-D-galactoside galactohydrolase; Catalyzes the hydrolysis of melibiose and alpha-galactosides of the raffinose family of oligosaccharides (RFOs) such as raffinose and stachyose. Cannot act on polymeric substrates such as locust bean gum; Belongs to the glycosyl hydrolase 4 family.
  
  
 0.887
amyD
Carbohydrate ABC transporter (permease); Part of the ABC transporter complex MelEDC-MsmX involved in melibiose, raffinose and stachyose import. Probably responsible for the translocation of the substrate across the membrane.
 
    0.885
amyC
Maltose and multiple sugars ABC transporter (permease); Part of the ABC transporter complex MelEDC-MsmX involved in melibiose, raffinose and stachyose import. Probably responsible for the translocation of the substrate across the membrane.
 
    0.867
ccpB
Transcriptional repressor of carbon supply (LacI family); Transcriptional regulator involved in catabolite repression of several operons.
  
     0.773
rsgI
sigmaI modulating factor; Anti-sigma factor for SigI. Negatively regulates SigI activity through direct interaction.
      
 0.681
pssA
Phosphatidylserine synthase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
      
 0.580
licA
Phosphotransferase system (PTS) lichenan-specific enzyme IIA component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane. This system is involved in lichenan transport.
   
  
 0.508
galK
Galactokinase; Catalyzes the transfer of the gamma-phosphate of ATP to D- galactose to form alpha-D-galactose-1-phosphate (Gal-1-P). Belongs to the GHMP kinase family. GalK subfamily.
 
  
 0.500
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.
