Target type: molecularfunction
Enables the transfer of L-lysine from one side of a membrane to the other. L-lysine is 2,6-diaminohexanoic acid. [GOC:ai, GOC:mtg_transport, ISBN:0815340729]
L-lysine transmembrane transporter activity refers to the process by which a protein embedded within the cell membrane facilitates the movement of the amino acid L-lysine across the membrane. This transport is typically driven by a concentration gradient, meaning L-lysine moves from an area of high concentration to an area of low concentration. The transporter protein binds to L-lysine on one side of the membrane, undergoes a conformational change, and then releases L-lysine on the other side. This process is essential for cells to take up L-lysine, which is an essential amino acid that cannot be synthesized by the body and must be obtained from the diet. L-lysine is used in the synthesis of proteins, enzymes, and other essential molecules. Transporters specific for L-lysine are crucial for maintaining appropriate levels of this amino acid in cells, and disruptions in their function can lead to various metabolic disorders.'
