ACOX3 (Acyl-CoA Oxidase 3) is a peroxisomal enzyme involved in the β-oxidation of branched-chain fatty acids and specific long-chain polyunsaturated fatty acids. It belongs to the acyl-CoA oxidase family, which catalyzes the first and rate-limiting step of fatty acid oxidation by converting acyl-CoA esters to trans-2-enoyl-CoA, generating hydrogen peroxide as a byproduct. Unlike ACOX1 and ACOX2. which primarily target straight-chain and bile acid intermediates, respectively, ACOX3 exhibits substrate specificity for methyl-branched fatty acids, such as phytanic acid, and certain very-long-chain fatty acids. This functional specialization links ACOX3 to lipid metabolism regulation and cellular energy homeostasis.
Recombinant ACOX3 protein is engineered through heterologous expression systems (e.g., E. coli, mammalian cells) to study its enzymatic properties, structural features, and pathological relevance. Its production enables detailed biochemical characterization, including kinetic parameters, substrate preferences, and inhibitor screening. Researchers utilize recombinant ACOX3 to investigate peroxisomal disorders like rhizomelic chondrodysplasia punctata (RCDP) and Refsum disease, where impaired branched-chain fatty acid oxidation contributes to neurological and developmental abnormalities. Additionally, studies suggest ACOX3 dysregulation may influence cancer progression and neurodegenerative diseases, though mechanistic insights remain incomplete.
The recombinant protein also serves as an antigen for antibody development and diagnostic tools. Advances in protein engineering have improved its stability and catalytic efficiency, facilitating high-throughput assays and drug discovery platforms targeting lipid metabolism pathways. Ongoing research focuses on elucidating ACOX3's role in inflammatory responses and its potential as a biomarker for metabolic syndromes. Despite progress, challenges persist in understanding tissue-specific expression patterns and post-translational modifications affecting its activity in vivo.
