Reaction: ATP + H2O + aliphatic sulfonate-[sulfonate-binding protein][side 1] = ADP + phosphate + aliphatic sulfonate[side 2] + [sulfonate-binding protein][side 1]
Other name(s): aliphatic sulfonate transporting ATPase; alkane sulfonate ABC transporter; aliphatic sulfonate ABC transporter; ssuACB (gene names)
Systematic name: ATP phosphohydrolase (ABC-type, aliphatic sulfonate-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. The enzyme from the bacterium Escherichia coli K-12 interacts with an extracytoplasmic substrate binding protein and imports a broad range of aliphatic sulfonates for use as a source of sulfur.
