SPR Protein, Human

Cat. No.: HY-P701862
Handling Instructions

SPR proteins play a key role in tetrahydrobiopterin biosynthesis by catalyzing the final one or two reductions required to form 5,6,7,8-tetrahydrobiopterin. This enzyme activity is critical for the production of tetrahydrobiopterin, a cofactor involved in various biochemical pathways, including neurotransmitter synthesis and nitric oxide production. SPR Protein, Human is the recombinant human-derived SPR protein, expressed by E. coli , with tag free. The total length of SPR Protein, Human is 261 a.a., .

Background

Sapropterin reductase (SPR) is an enzyme that plays a crucial role in the biosynthesis of tetrahydrobiopterin (BH4). Specifically, SPR catalyzes the final one or two reductions in the tetrahydrobiopterin biosynthetic pathway, ultimately forming 5,6,7,8-tetrahydrobiopterin. This co-factor is essential for the activity of aromatic amino acid hydroxylases, which are involved in the synthesis of neurotransmitters and other bioactive molecules. The catalytic activity of SPR is vital for maintaining appropriate levels of tetrahydrobiopterin, which, in turn, influences the proper functioning of various physiological processes, including neurotransmitter production. Dysregulation of BH4 biosynthesis can impact neurotransmitter homeostasis and has been implicated in certain neurological disorders. It has to succinctly outline SPR's role in the final steps of tetrahydrobiopterin biosynthesis, underscoring its importance in supporting crucial biochemical pathways.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
