Enzyme Information
7.5.2.1 |
ABC-type maltose transporter.
based on mapping to UniProt P68187
ATP + H(2)O + maltose-[maltose-binding protein](Side 1) = ADP + phosphate + maltose(Side 2) + [maltose-binding protein](Side 1).
-!- 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. -!- Formerly EC 3.6.3.19.
