EC 7.5.2.1 Details

show Brenda entry

EC number

7.5.2.1

Accepted name

ABC-type maltose transporter

Reaction

ATP + H₂O + maltose-[maltose-binding protein]_{[side 1]} = ADP + phosphate + maltose_{[side 2]} + [maltose-binding protein]_{[side 1]}

Other name(s)

maltose ABC transporter, maltose-transporting ATPase

Systematic name

ATP phosphohydrolase (ABC-type, maltose-importing)

Comment

An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. The enzyme, found in bacteria, interacts with an extracytoplasmic substrate binding protein and mediates the import of maltose and maltose oligosaccharides.

History

created 2000 as EC 3.6.3.19, transferred 2018 to EC 7.5.2.1
