Overview

Basic information about this protein and its source genome.

Accession: PA3228
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA3228
Status: annotated
Amino acids: 610
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:0140359 Primary active transporter characterized by two nucleotide-binding domains and two transmembrane domains. Uses the energy generated from ATP hydrolysis to drive the transport of a substance across a membrane. GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. GO:0016887 Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient. GO:0034040 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + lipid(in) = ADP + phosphate + lipid(out). GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other.
