EC 18.104.22.168, SAHH, AdoHcyase, S-adenosyl-L-homocysteine hydrolase, Adenosylhomocysteinase.
AHCY is an enzyme that catalyzes the reversible hydrolysis of S-adenosylhomocysteine (AdoHcy) to adenosine (Ado) and L-homocysteine (Hcy). AHCY controls the intracellular S-adenosylhomocysteine (SAH) concentration that is crucial for transmethylation reactions. AHCY deficiency causes hypermethioninemia.
AHCY Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 456 amino acids (1-432 a.a) and having a molecular mass of 50.2kDa.
AHCY is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Sterile filtered colorless solution.
AHCY protein solution (0.25mg/ml) containing 20mM Tris-Hcl buffer (pH8.0) containing 40% glycerol 0.2M NaCl, 1mM DTT.
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
