Dextranase, identified by its CAS number 9025-70-1, is a remarkable enzyme with significant industrial applications. As a key player in the hydrolysis of dextrans, understanding its scientific underpinnings—from its enzymatic mechanism to its stability and optimal sourcing—is essential for researchers and industrial users alike. For those looking to buy Dextranase, partnering with knowledgeable manufacturers and suppliers is key to accessing its full potential.

Enzymatic Mechanism of Dextranase

At its core, Dextranase belongs to the glycoside hydrolase family, specifically targeting the α-1,6 glucosidic bonds that form the backbone of dextran. This endo-acting enzyme cleaves the long dextran chains into smaller oligosaccharides, primarily isomaltose (a disaccharide) and isomalto-oligosaccharides, as well as glucose. This specific cleavage action is what makes Dextranase invaluable in applications where dextran's presence causes undesirable viscosity or processing difficulties.

Factors Affecting Dextranase Stability and Activity

The efficacy of Dextranase is influenced by several environmental factors, and understanding these helps in optimizing its use. Key factors include:

  • pH: Dextranase exhibits varying pH optima depending on its microbial source. Generally, enzymes derived from bacteria perform optimally in a pH range of 6.0-9.0, while mold-derived enzymes prefer slightly more acidic conditions, typically pH 4.0-5.0. It's common for Dextranase to show good stability in neutral to slightly alkaline environments (pH 6-9).
  • Temperature: Temperature is another critical parameter. While many Dextranase preparations are active across a broad range (e.g., 40-80°C), their optimal activity and stability are usually within a narrower band. High temperatures can lead to denaturation and loss of activity.
  • Presence of Ions: The stability of Dextranase can be significantly enhanced by the presence of certain metal ions, notably calcium (Ca2+). Calcium ions can help protect the enzyme structure, increasing its heat resistance and overall stability.
  • Formulation: Enzyme preparations can be formulated as powders or liquids. Liquid formulations often contain stabilizers like glycerol (40-60%), which help prevent activity decline and maintain enzyme integrity during storage and transport.
