The directed movement of branched-chain amino acids into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Branched-chain amino acids are amino acids with a branched carbon skeleton without rings.

The directed movement of phenylalanine, 2-amino-3-phenylpropanoic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of isoleucine across a membrane.

The directed movement of L-valine across a membrane.

The directed movement of D-alanine, the D-enantiomer of 2-aminopropanoic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of L-alanine, the L-enantiomer of 2-aminopropanoic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of L-valine from outside of a cell, across the plasma membrane and into the cytosol.

The directed movement of L-isoleucine from outside of a cell, across the plasma membrane and into the cytosol.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

A complex for the transport of metabolites into the cell, consisting of 5 subunits: two ATP-binding subunits, two membrane spanning subunits, and one substrate-binding subunit. In organisms with two membranes, the substrate-binding protein moves freely in the periplasmic space and joins the other subunits only when bound with substrate. In organisms with only one membrane the substrate-binding protein is tethered to the cytoplasmic membrane and associated with the other subunits. Transport of the substrate across the membrane is driven by the hydrolysis of ATP.
