Recombinant Human CBS Protein, also known as Cystathionine beta-synthase, is a key enzyme involved in the metabolism of sulfur-containing amino acids. It plays a crucial role in maintaining the balance of homocysteine, cysteine, and glutathione in the body. This protein is produced through recombinant DNA technology, making it a highly pure and stable form of the enzyme. In this article, we will explore the structure, activity, and application of Recombinant Human CBS Protein.
The Recombinant Human CBS Protein is a homotetramer, meaning it is composed of four identical subunits. Each subunit is made up of 551 amino acids and has a molecular weight of approximately 63 kDa. The overall structure of the protein is similar to other pyridoxal 5′-phosphate-dependent enzymes, with a central beta-sheet surrounded by alpha-helices.
The active site of Recombinant Human CBS Protein is located at the interface of the four subunits. It contains a pyridoxal 5′-phosphate (PLP) cofactor, which is essential for the catalytic activity of the enzyme. The PLP cofactor is bound to the protein through a Schiff base linkage with a lysine residue, and it plays a crucial role in the conversion of homocysteine to cystathionine.
The primary function of Recombinant Human CBS Protein is to catalyze the condensation of homocysteine and serine to form cystathionine. This reaction is the first step in the transsulfuration pathway, which converts homocysteine to cysteine. This process is essential for the production of glutathione, a powerful antioxidant that protects cells from oxidative stress.
In addition to its role in sulfur amino acid metabolism, Recombinant Human CBS Protein also has a secondary activity in the conversion of homocysteine to methionine. This reaction, known as the remethylation pathway, helps to maintain the balance of homocysteine in the body and prevent the accumulation of toxic levels of this amino acid.
Recombinant Human CBS Protein has a wide range of applications in both research and clinical settings. In research, it is commonly used to study the structure and function of the enzyme and to investigate the role of CBS mutations in diseases such as homocystinuria and hyperhomocysteinemia.
In clinical settings, Recombinant Human CBS Protein is used for diagnostic purposes. Mutations in the CBS gene can lead to deficiencies in the enzyme, resulting in elevated levels of homocysteine and a range of health problems. Measurement of CBS activity using Recombinant Human CBS Protein can help to diagnose these conditions and monitor their progression.
Furthermore, Recombinant Human CBS Protein has potential therapeutic applications. It has been used in preclinical studies to treat homocystinuria and hyperhomocysteinemia, with promising results. The enzyme has also been investigated as a potential target for drug development to treat other conditions, such as cardiovascular disease and neurodegenerative disorders.
In summary, Recombinant Human CBS Protein is a crucial enzyme involved in sulfur amino acid metabolism. Its structure, activity, and applications make it a valuable tool for research and clinical purposes. With ongoing research and development, this protein has the potential to make a significant impact in the diagnosis and treatment of various diseases and disorders.
