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

melAAlpha-galactosidase, NAD(P)-binding; Alpha-galactosidase; Protein involved in carbohydrate catabolic process and NAD biosynthetic process; Belongs to the glycosyl hydrolase 4 family. (451 aa)    
Predicted Functional Partners:
melB
Melibiose:sodium symporter; Responsible for melibiose and other galactoside transport. It is capable of using hydrogen, sodium, and lithium cations as coupling cations for cotransport, depending on the particular sugar transported (symport system).
  
  
 0.986
ebgA
Evolved beta-D-galactosidase, alpha subunit; The wild-type enzyme is an ineffective lactase. Two classes of point mutations dramatically improve activity of the enzyme; Belongs to the glycosyl hydrolase 2 family.
 
 
 0.938
lacZ
beta-D-galactosidase; Protein involved in carbohydrate catabolic process; Belongs to the glycosyl hydrolase 2 family.
 
 
 0.920
malZ
Maltodextrin glucosidase; May play a role in regulating the intracellular level of maltotriose. Cleaves glucose from the reducing end of maltotriose and longer maltodextrins with a chain length of up to 7 glucose units.
   
 
 0.907
galM
Aldose 1-epimerase; Mutarotase converts alpha-aldose to the beta-anomer. It is active on D-glucose, L-arabinose, D-xylose, D-galactose, maltose and lactose.
   
 
 0.903
ebgC
Evolved beta-D-galactosidase, beta subunit; Required for full activity of the EbgA enzyme. Exact function not known.
     
  0.900
yihR
Putative sulphoquinovose mutarotase; Putative aldose-1-epimerase.
   
 
  0.900
melR
Melibiose operon transcriptional regulator; Transcription activator for the expression of the melAB operon. MelR binds at two sites located upstream of the melAB transcription site.
 
  
 0.830
mngB
Alpha-mannosidase; May hydrolyze 6-phospho-mannosyl-D-glycerate to mannose-6- phosphate and glycerate; Belongs to the glycosyl hydrolase 38 family.
     
 0.754
aes
Acetyl esterase; Displays esterase activity towards short chain fatty esters (acyl chain length of up to 8 carbons). Able to hydrolyze triacetylglycerol (triacetin) and tributyrylglycerol (tributyrin), but not trioleylglycerol (triolein) or cholesterol oleate. Negatively regulates MalT activity by antagonizing maltotriose binding. Inhibits MelA galactosidase activity.
