MetaCyc Pathway: melibiose degradation

This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.

Superclasses: Degradation/Utilization/Assimilation Carbohydrates Degradation Sugars Degradation

Some taxa known to possess this pathway include ? : Escherichia coli K-12 substr. MG1655

Expected Taxonomic Range: Archaea , Bacteria , Eukaryota

Summary:
Escherichia coli is able to utilize melibiose as a sole source of carbon. Melibiose is imported by the melibiose permease, MelB. The melibiose is then converted to β-D-glucose and β-D-galactose by the α-galactosidase encoded by melA.
