**Background of ACY2 Recombinant Protein**
Acylaminoacyl peptidase 2 (ACY2), also known as aminoacylase-2. is a zinc-dependent hydrolase belonging to the M20 metalloprotease family. It plays a critical role in cellular metabolism by catalyzing the hydrolysis of N-acylated amino acids, specifically removing acetyl groups from acetylated amino acids. This activity links ACY2 to the regulation of amino acid recycling and detoxification pathways, particularly in the kidney and liver, where it is predominantly expressed.
The recombinant ACY2 protein is engineered through molecular cloning techniques, where the *ACY2* gene is expressed in heterologous systems like *E. coli* or mammalian cell lines. This allows large-scale production of purified, functional enzyme for research and therapeutic applications. Recombinant ACY2 retains the enzymatic properties of the native protein, including substrate specificity and metal ion dependency, making it valuable for studying amino acid metabolism disorders, such as acylase deficiency, which can lead to metabolic acidosis or neurological impairments.
In biomedical research, recombinant ACY2 is used to investigate its role in diseases like cancer, where altered amino acid metabolism is a hallmark. It also serves as a tool for structural studies to elucidate substrate-binding mechanisms and zinc coordination, aiding in drug design. Additionally, its potential as a biomarker or therapeutic target in metabolic syndromes is under exploration.
Overall, recombinant ACY2 provides a versatile platform to decode its physiological functions and pathological implications, bridging basic science with clinical applications.
