Accepted name: ABC-type molybdate transporter
Reaction: ATP + H2O + molybdate-[molybdate-binding protein][side 1] = ADP + phosphate + molybdate[side 2] + [molybdate-binding protein][side 1]
Glossary: molybdate = tetraoxidomolybdate(2-) = MoO42-
Other name(s): molybdate ABC transporter; molybdate-transporting ATPase
Systematic name: ATP phosphohydrolase (ABC-type, molybdate-importing)
Comments: 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 high-affinity import of molybdate and tungstate. Does not undergo phosphorylation during the transport process.
