EC 3.6.3.55 Details

show Brenda entry

EC number

3.6.3.55

Accepted name

tungstate-importing ATPase

Reaction

ATP + H₂O + tungstate_{[side 1]} = ADP + phosphate + tungstate_{[side 2]}

Other name(s)

tungstate transporter, WtpABC, TupABC, tungstate-specific ABC transporter

Systematic name

ATP phosphohydrolase (tungstate-importing)

Comment

An ABC-type (ATP-binding cassette-type) ATPase. The enzymes from the archaeon Pyrococcus furiosus, the Gram-positive bacterium Eubacterium acidaminophilum and the Gram-negative bacterium Campylobacter jejuni transport tungsten into the cell for incorporation into tungsten-dependent enzymes.
