Overview

Basic information about this protein and its source genome.

Accession: PA5291
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA5291
Status: annotated
Amino acids: 661
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:0005275 Enables the transfer of amines, including polyamines, from one side of a membrane to the other. Amines are organic compounds that are weakly basic in character and contain an amino (-NH2) or substituted amino group. GO:0015653 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: glycine betaine(out) + H+(out) = glycine betaine(in) + H+(in). GO:0022857 Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. GO:0071475 Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detection of, or exposure to, an increase in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment. GO:0031460 The directed movement of glycine betaine, N-trimethylglycine, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
