Scientific Description

Maltose Phosphorylase from Enterococcus sp. (Catalog B2013883, 250 units, ~90 kDa powder) belongs to glycoside hydrolase family 65 and catalyzes the reversible conversion of maltose and inorganic phosphate into D-glucose and β-D-glucose-1-phosphate, a key reaction in carbohydrate metabolism . Supplied as a highly pure biotechnology-grade powder, stored at –20 °C, this enzyme is engineered to support precise dosing and long-term stability.

In research applications, this phosphorylase serves as a valuable tool for characterizing maltose metabolism, designing biosensors, and probing glycosyl transfer mechanisms. It’s frequently employed in enzymatic assays to monitor phosphate release or glucose formation and in synthetic biochemistry workflows where glucosyl transfers are explored. Its defined activity and purity streamline integration with SOPs and LIMS environments.

Typical uses include developing assays to measure α-amylase activity, evaluating phosphate biosensing platforms, and engineering glycosylation reactions. The enzyme’s family-65 classification hints at structural and mechanistic traits shared with related glycosyltransferases, providing a biochemical foundation for mutagenesis or enzymology studies.

Why researchers choose this product:

  • Precise 250 unit fill in a stable powder form for accurate dosing
  • Efficiently catalyzes maltose + Pi → D-glucose + glucose-1-phosphate, enabling metabolic and assay workflows
  • Biotechnology-grade purity filtered through ultrapure water systems ensures minimal contamination
  • Stored at –20 °C to preserve activity and support reproducibility in cold-chain systems

This product is for Research Use Only (RUO). It is not intended for diagnostic or therapeutic use.
