**Background of ACSS1 Recombinant Protein**
Acetyl-CoA synthetase 1 (ACSS1) is a mitochondrial enzyme critical for cellular energy metabolism. It catalyzes the conversion of acetate into acetyl-CoA, a key substrate for the tricarboxylic acid (TCA) cycle and oxidative phosphorylation. This reaction links acetate utilization to ATP production, particularly in tissues with high energy demands, such as the liver, heart, and skeletal muscle. ACSS1’s role is vital under metabolic stress, such as fasting or hypoxia, where acetate serves as an alternative carbon source. Dysregulation of ACSS1 has been implicated in metabolic disorders, neurodegenerative diseases, and cancer, highlighting its broader physiological significance.
Recombinant ACSS1 protein is engineered through molecular cloning and expression in heterologous systems (e.g., *E. coli* or mammalian cells) to produce purified, functional enzyme for research. This allows precise study of its structure, enzymatic kinetics, and interactions. Recombinant ACSS1 retains the ability to bind ATP, acetate, and CoA, facilitating investigations into its catalytic mechanisms and regulation by post-translational modifications or metabolic signals.
Studies using recombinant ACSS1 have advanced understanding of mitochondrial metabolism, including how acetate recycling impacts lipid synthesis, histone acetylation, and cellular redox balance. In disease models, ACSS1 dysregulation correlates with altered acetyl-CoA pools, influencing gene expression and metabolic flexibility. For example, reduced ACSS1 activity in neurons is linked to impaired acetate metabolism in Alzheimer’s disease, while cancer cells may exploit ACSS1 to sustain proliferation under nutrient-limited conditions.
Overall, recombinant ACSS1 serves as a valuable tool for exploring metabolic pathways, disease mechanisms, and potential therapeutic strategies targeting acetyl-CoA metabolism.
