The chemical reactions and pathways resulting in the breakdown of glycine betaine, N-trimethylglycine.

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.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating an increase or decrease in the concentration of solutes outside the organism or cell.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cold stimulus, a temperature stimulus below the optimal temperature for that organism.

The directed movement of carnitine into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Carnitine is a compound that participates in the transfer of acyl groups across the inner mitochondrial membrane.

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.

The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).

A complex for the transport of metabolites into and out of the cell, typically comprised of four domains; two membrane-associated domains and two ATP-binding domains at the intracellular face of the membrane, that form a central pore through the plasma membrane. Each of the four core domains may be encoded as a separate polypeptide or the domains can be fused in any one of a number of ways into multidomain polypeptides. In Bacteria and Archaebacteria, ABC transporters also include substrate binding proteins to bind substrate external to the cytoplasm and deliver it to the transporter.
