Function
function
Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system.
Catalytic activity
- phosphate(out) + ATP + H2O = ADP + 2 phosphate(in) + H+phosphate (out)CHEBI:43474
+ CHEBI:30616 + CHEBI:15377 = CHEBI:456216 + 2 phosphate (in)CHEBI:43474+ CHEBI:15378
