Target type: molecularfunction
Binding to a long-chain fatty acid. A long-chain fatty acid has an aliphatic tail containing 13 to 22 carbons. [GOC:pm, PMID:12641450]
Long-chain fatty acid binding is a molecular function that involves the interaction of proteins with long-chain fatty acids, which are fatty acids with a carbon chain length of 12 or more carbons. These interactions are crucial for a wide range of biological processes, including:
* **Lipid metabolism:** Long-chain fatty acids are essential components of cell membranes, and their binding to specific proteins facilitates their transport, storage, and utilization.
* **Signal transduction:** Fatty acids can act as signaling molecules, triggering cellular responses by binding to specific receptors or modifying the activity of enzymes.
* **Protein folding and stability:** The binding of fatty acids to proteins can influence their folding, stability, and overall activity.
* **Cellular trafficking:** Fatty acids can mediate the movement of proteins and other molecules within cells.
* **Inflammation and immunity:** Fatty acids play a role in modulating inflammation and immune responses, with some fatty acids having anti-inflammatory effects while others can promote inflammation.
* **Cellular stress response:** Fatty acid binding can be involved in the cellular response to stress conditions, such as oxidative stress.
The mechanism of long-chain fatty acid binding often involves hydrophobic interactions between the fatty acid tail and non-polar amino acid residues in the protein. This hydrophobic interaction is driven by the tendency of non-polar molecules to avoid contact with water. Additionally, specific residues within the binding site can form hydrogen bonds or electrostatic interactions with the fatty acid head group, further contributing to the binding affinity.
The specific details of the binding process vary depending on the protein and the specific fatty acid involved. However, the fundamental principle of hydrophobic interactions and specific residue interactions provides a basis for understanding the molecular mechanisms of long-chain fatty acid binding in a wide range of proteins.'
