show Brenda entryEC number
7.2.2.4
Accepted name
ABC-type Na+ transporter
Reaction
ATP + H2O + Na+[side 1] = ADP + phosphate + Na+[side 2]
Other name(s)
natAB (gene names)
Systematic name
ATP phosphohydrolase (ABC-type, Na+-exporting)
Comment
ABC-type (ATP-binding cassette-type) transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. This bacterial enzyme, characterized from Bacillus subtilis, exports Na+ ions out of the cell. cf. EC 7.2.2.1, Na+-transporting two-sector ATPase and EC 7.2.2.3, P-type Na+ transporter.
