Activity summary

OXSM also known as 3-oxoacyl-[acyl-carrier-protein] synthase mitochondrial is an important enzyme in the mitochondrial fatty acid synthesis pathway. It participates in the elongation of fatty acids by catalyzing a ketoacyl synthesis reaction. This protein has a molecular mass of approximately 50 kDa. OXSM is mainly expressed in tissues with high metabolic activity such as liver and muscle tissues where it supports the dynamic balance of fatty acid synthesis.

Biological function summary

OXSM plays a part in mitochondrial lipid homeostasis by facilitating the synthesis of longer chain fatty acids. It operates as part of a multiprotein complex that ensures proper substrate channeling and processing. This function is critical for the maintenance and functioning of cellular membranes providing the necessary lipid components. Additionally OXSM contributes to energy production by generating fatty acids that can be converted into acetyl-CoA units within the mitochondria.

Pathways

Several metabolic pathways involve OXSM including the mitochondrial fatty acid synthesis and the broader lipid metabolism pathway. In the mitochondrial fatty acid synthesis pathway OXSM interacts with proteins like Acyl-CoA synthetase family member 1 (ACSF1) to facilitate the progression of fatty acid synthesis. These pathways collectively contribute to energy homeostasis and cellular membrane composition reflecting the interconnectivity between various metabolic functions.

Associated diseases and disorders

Researchers associate OXSM with rare mitochondrial disorders linked to lipid metabolism. For instance mutations or dysfunctions in OXSM can result in compromised mitochondrial function potentially contributing to neuromuscular disorders. It also connects to carnitine palmitoyltransferase 1A (CPT1A) another key enzyme in fatty acid metabolism which highlights the interconnected nature of mitochondrial metabolic disorders. Understanding OXSM's role in these conditions can lead to better insights for therapeutic strategies.
