제품 세부 정보

Cystathionine beta Synthase Assay Kit (ab241043) utilizes cysteine and homocysteine as substrates to produce H2S. Hydrogen sulfide reacts with the azido-functional group of the fluorescent probe yielding a fluorescent amino group (Ex/Em = 368/460 nm). The assay is highly sensitive, has a simple easy-to-follow protocol, and can detect as low as 1.45 mU of CBetaS activity.

Cystathionine beta-synthase (CBS) is an enzyme that catalyzes the conversion of homocysteine and serine into cystathionine. It is sometimes referred to as CBS monelyne or cystathionine synthase. CBS is a heme-containing protein with a molecular mass of approximately 63 kDa. It is expressed widely in tissues including the liver brain and kidney. The activity of CBS is regulated by various factors including the availability of cofactors like pyridoxal 5'-phosphate and adenosine triphosphate (ATP).
Biological function summary

The enzyme CBS plays a role in the transsulfuration pathway where it helps in the metabolism of homocysteine. CBS is a part of a larger complex in some tissues where it interacts with other enzymes involved in sulfur amino acid metabolism. This function is important in maintaining cellular sulfur amino acid balance and protecting cells from oxidative stress caused by elevated levels of homocysteine.

Pathways

CBS functions in the transsulfuration pathway which connects the methionine cycle and the synthesis of glutathione. This pathway is essential for detoxification and antioxidant protection. CBS interrelates with other proteins like cystathionine gamma-lyase (CGL) within this pathway. The interplay between CBS and CGL ensures the conversion of homocysteine to cysteine which is a precursor for the synthesis of glutathione.

CBS deficiency is linked to homocystinuria a disorder characterized by high levels of homocysteine in the blood and urine. Symptoms include cardiovascular problems and developmental delays. Furthermore alterations in CBS activity relate to cardiovascular diseases due to hyperhomocysteinemia. Within these conditions CBS interacts with other proteins involved in homocysteine metabolism such as methionine synthase which also contributes to the complexity of these disorders.

타겟 정보

Hydro-lyase catalyzing the first step of the transsulfuration pathway, where the hydroxyl group of L-serine is displaced by L-homocysteine in a beta-replacement reaction to form L-cystathionine, the precursor of L-cysteine. This catabolic route allows the elimination of L-methionine and the toxic metabolite L-homocysteine (PubMed : 20506325, PubMed : 23974653, PubMed : 23981774). Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons (By similarity).
