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.

malA6-phospho-alpha-glucosidase; Hydrolyzes maltose-6'-phosphate and trehalose-6'-phosphate. Is involved in the catabolism of alpha-glycosides accumulated via a phosphoenolpyruvate-dependent maltose phosphotransferase system (PEP- PTS). Is also able to significantly catalyze the hydrolysis of both 6- phospho-alpha- and 6-phospho-beta-glucosides containing activated leaving groups such as p-nitrophenol and does so with retention and inversion, respectively, of the substrate anomeric configuration. (449 aa)    
Predicted Functional Partners:
malP
Phosphotransferase system (PTS) maltose-specific enzyme IICB 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. This system is involved in maltose transport.
 
 0.999
malR
Transcriptional activator of the Mal operon; Positive regulator of the glv operon expression, which consists of GlvA, GlvR and GlvC.
 
  
 0.993
treP
Phosphotransferase system (PTS) trehalose-specific enzyme IIBC 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. This system is involved in trehalose transport.
 
 
 0.937
mdxK
Maltose phosphorylase; Catalyzes the phosphorolysis of maltose, leading to the formation of glucose and glucose 1-P.
   
 
 0.922
ypqE
Putative phosphotransferase system enzyme 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.
    
 0.920
yyzE
Putative phosphotransferase system 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.
  
 
 0.914
treA
Trehalose-6-phosphate hydrolase; Hydrolyzes trehalose-6-phosphate to glucose and glucose 6- phosphate. Can also very effectively hydrolyzes p-nitrophenyl-alpha-D- glucopyranoside, but not lactose, maltose, sucrose or sucrose-6- phosphate. Trehalose is also hydrolyzed, but to a much smaller extent than trehalose-6-phosphate; Belongs to the glycosyl hydrolase 13 family.
   
 
 0.908
sacA
Sucrase-6-phosphate hydrolase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme; Belongs to the glycosyl hydrolase 32 family.
  
  
 0.694
mdxL
Oligo-1,4-1,6-alpha-glucosidase (sucrase-maltase-isomaltase); Hydrolyzes various disaccharides such as sucrose, maltose, and isomaltose with different efficiencies. Also hydrolyzes longer maltodextrins from maltotriose up to maltohexaose, but not maltoheptaose, palatinose, isomaltotriose, or isomaltotetraose. Belongs to the glycosyl hydrolase 13 family.
   
  
 0.657
mdxJ
Putative component of maltodextrin transporter; Could have a role in maltodextrin utilization.
   
  
 0.606
