Overview

Basic information about this protein and its source genome.

Accession: PA0450
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA0450
Status: annotated
Amino acids: 540
Structure source: AlphaFold

GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. GO:0005315 Enables the transfer of phosphate ions from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Secondary active transporters include symporters and antiporters. GO:0015293 Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. GO:0035435 The process in which a phosphate is transported across a membrane. GO:0006817 The directed movement of phosphate ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
