Accepted name: ABC-type D-galactose transporter
Reaction: ATP + H2O + D-galactose-[galactose-binding protein][side 1] = ADP + phosphate + D-galactose[side 2] + [galactose-binding protein][side 1]
Other name(s): D-galactose transporting ATPase; D-galactose ABC transporter; mglBAC (gene names)
Systematic name: ATP phosphohydrolase (ABC-type, D-galactose-importing)
Comments: ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme, best characterized from Escherichia coli where it interacts with a periplasmic substrate binding protein and mediates the high affinity uptake of D-galactose and methyl-β-D-galactoside.
