SCLY Protein, Human, Recombinant (His)

Catalog No. TMPY-03754

SCLY, also known as selenocysteine lyase, belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. It is a novel enzyme that exclusively decomposes L-selenocysteine into L-alanine and H2Se in various mammalian tissues. SCLY contains pyridoxal 5'-phosphate and weighs approximately 85,000. SCLY participates in selenoamino acid metabolism. It employs one cofactor, pyridoxal phosphate. Its maximum reactivity is at about pH 9.0. It was shown that 1 mol of selenocysteine is converted to equimolar amounts of alanine and H2Se. The following amino acids are insert: L-cysteine, L-serine, L-cysteine sulfinate, selenocysteamine, Se-ethyl-DL-selenocysteine, and L-selenohomocysteine. L-Cysteine (Ki, 1.0 mM) competes with L-selenocysteine (Km, 0.83mM) to inhibit the enzyme reaction.

Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris, 500 mM NaCl, 10% glycerol, pH 8.0.Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
