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.

melBGPH family melibiose permease II; Responsible for melibiose transport. It is capable of using hydrogen, sodium, and lithium cations as coupling cations for cotransport, depending on the particular sugar transported (symport system); Belongs to the sodium:galactoside symporter (TC 2.A.2) family. (476 aa)    
Predicted Functional Partners:
crr
Glucose-specific IIA component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II complex composed of PtsG and Crr is involved in glucose transport. It can also phosphorylate mannose, methyl alpha-glucoside and 2-deoxy-glucose. The non-phosphorylated EIII-Glc is an inhibitor for uptake of certain sugars such as maltose, melibiose, lactose, and glycerol. Phosphorylated EIII-Glc [...]

melR
AraC/XylS family; similar to E. coli regulator of melibiose operon (AAC77079.1); Blastp hit to AAC77079.1 (302 aa), 88% identity in aa 4 - 302.
 
  
 0.866
melA
Alpha-galactosidase. (SW:AGAL_SALTY); Belongs to the glycosyl hydrolase 4 family.
  
  
 0.807
STM0257
Putative drug efflux protein (perhaps for chloramphenicol); Similar to E. coli putative transport protein (AAC74729.1); Blastp hit to AAC74729.1 (389 aa), 41% identity in aa 7 - 378.
      
 0.679
bcfB
Fimbrial chaperone (gi|4959512).
   
  
 0.652
gabP
APC family; similar to E. coli transport permease protein of gamma-aminobutyrate (AAC75710.1); Blastp hit to AAC75710.1 (466 aa), 92% identity in aa 1 - 466.
   
  
 0.559
malK
Maltose transport protein; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Maltooligosaccharide importer (TC 3.A.1.1.1) family.
   
  
 0.532
malM
Periplasmic protein of mal regulon; Not yet known. Might function in the uptake of a still unidentified substrate; To E.coli MalM.
   
  
 0.477
glpK
Glycerol kinase; Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate.
     
 0.454
