aromatic amino acid transmembrane transporter activity

Definition

Target type: molecularfunction

Enables the transfer of aromatic amino acids from one side of a membrane to the other. Aromatic amino acids have an aromatic ring. [GOC:ai, GOC:mtg_transport, ISBN:0815340729]

Aromatic amino acid transmembrane transporter activity is a molecular function that describes the ability of a protein to transport aromatic amino acids across cellular membranes. These amino acids, including phenylalanine, tyrosine, and tryptophan, are essential building blocks for proteins and play crucial roles in various cellular processes. The transporters facilitate the movement of these amino acids against their concentration gradients, requiring energy derived from ATP hydrolysis. This process ensures the efficient uptake and distribution of aromatic amino acids within cells, supporting vital functions such as protein synthesis, neurotransmission, and hormone production. The transporter proteins typically exhibit high specificity for their aromatic amino acid substrates, ensuring accurate delivery to their target compartments. These transporters operate within a complex network of membrane transport systems, contributing to maintaining cellular homeostasis and ensuring the proper functioning of diverse biological pathways.'

levodopaL-dopa : An optically active form of dopa having L-configuration. Used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinson's disease

Levodopa: The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.		amino acid zwitterion;
