beta 1,3 Galactosidase (His tag)

beta 1,3 Galactosidase (β-1,3-半乳糖苷酶) 主要功能在於水解含 β-1,3 鍵結的半乳糖苷結構。此酵素在半乳寡糖 (Galactooligosaccharides, GOS) 的生產過程中擔任著核心角色。值得注意的是,半乳寡糖不僅是一種重要的功能性成分,更是多種益生菌的主要營養源,對於維護腸道健康具有關鍵性的影響。

  • Official Name: beta 1,3 Galactosidase
  • Specificity: beta 1,3 Galactosidase catalyzes the hydrolysis of terminal β1,3-linked galactose (Gal) from oligosaccharides and glycoprotein substrates. No detectable activities of proteases or other glycosidases are observed.
  • Content: Purified lyophilized powder
  • Tag: 8x His tag at N-term, which can be removed by digestion with FasTEV
  • Reconstitution: Dissolve the lyophilized product in 100 μL molecular grade water to make a 20,000 units/mL solution in the buffer.
  • Buffer: 20 mM Tris-HCl, 50 mM NaCl, 1 mM EDTA, pH 7.5
  • Storage: -20 °C as powder. Once reconstituted, 4 °C for seven days  or -20 °C for up to three months. Avoid freeze-thaw cycles.
  • Unit Definition: One unit is defined as the amount of β1,3 Galactosidase required to catalyze the release of 1 nmole p-nitrophenol (pNP) from p-nitrophenyl-β-D-galactopyranoside (pNP-Gal) in 10 min at 37°C in 100 μL 1X Reaction Buffer 1 (20 mM Tris, 50 mM NaCl, 1 mM EDTA pH 7.5).
