Summary
Long-chain and very long-chain acyl-CoA synthetases (ACSL/ACSVL) have distinct functions. Research is exploring their structure, modifications, and roles in fatty acid metabolism and transport.
Area of Science:
- Biochemistry
- Molecular Biology
- Cellular Metabolism
Background:
- The 11 long-chain (ACSL) and very long-chain acyl-CoA synthetases (ACSVL) are crucial enzymes in fatty acid metabolism.
- Emerging evidence indicates that these enzymes do not possess redundant functions, highlighting their specific roles.
Purpose of the Study:
- To review recent findings on the structure, post-translational modifications, and enzymatic activities of ACSL and ACSVL isoforms.
- To address the ongoing debate regarding the dual enzymatic and transport functions of ACSVL isoforms.
- To investigate the role of acyl-CoA synthesis in activating AMP-activated kinase.
Main Methods:
- Review of recent scientific literature focusing on ACSL and ACSVL enzymes.
- Analysis of studies investigating enzyme structure, post-translational modifications (phosphorylation, acetylation), and substrate specificity.
- Examination of research on fatty acid activation and metabolic pathway direction.
Main Results:
- Recent studies have elucidated the structure and post-translational modifications of acyl-CoA synthetases.
- The ability of these enzymes to activate fatty acids of varying chain lengths and direct them into metabolic pathways has been investigated.
- Controversy remains regarding the dual functions of ACSVL isoforms and the impact of acyl-CoA synthesis on AMP-activated kinase activation.
Conclusions:
- Further research is needed to determine the subcellular localization and functional significance of ACSL and ACSVL isoforms.
- Purification and crystallization of mammalian ACSL and ACSVL are required to elucidate their mechanisms of action and substrate affinities.
- Understanding how ACSL isoforms direct acyl-CoA products to specific downstream pathways is critical.

01:28Overview of Fatty Acid Metabolism
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

01:19Regulation of Metabolism
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...
02:36The Citric Acid Cycle
The citric acid cycle, also known as the Krebs cycle or TCA cycle, consists of several energy-generating reactions that yield one ATP molecule, three NADH molecules, one FADH2 molecule, and two CO2 molecules.
01:29Amino Acid Biosynthetic Pathways
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which provide...
01:28The Citric Acid Cycle: Output
The citric acid cycle is termed an amphibolic pathway as it operates both anabolically and catabolically. The cyclic reactions balance the flux of the substrates to provide an optimal concentration of NADH and ATP to the cell.
Regulation of Citric Acid Cycle
The citric acid cycle is regulated in several ways, including feedback inhibition, regulation of enzyme activities, and associated anaplerotic or cataplerotic pathways.
The primary substrate of the TCA cycle—acetyl CoA—is produced by the...

01:18Amino Acid Catabolism
Microorganisms rely on proteins as an essential carbon and energy source, particularly in environments with limited polysaccharides or lipids. However, proteins are too large to cross the plasma membrane unaided, necessitating enzymatic degradation. Microbes secrete extracellular proteases and peptidases that hydrolyze proteins into peptides, which can then be transported across the membrane. Once inside the cell, intracellular proteases degrade these peptides into free amino acids, which...
