General description

Maltose phosphorylase (MP) is a dimeric enzyme. This enzyme is classified under family 65 of the glycoside hydrolases. It is a member of the disaccharide phosphorylase family.

Application

Maltose Phosphorylase from Enterococcus sp. has been used as a component in coupled assay and ATPase activity assay to study its effects on ATPase activity, on the 90 kDa heat shock proteins (Hsp90) ATPase reaction and on background absorbance on the production of resorufin.
Maltose phosphorylase from Enterococcus has been used in a study to describe a new pathway for maltose utilization in lactic acid bacteria. It has also been used in a study to describe the transfer of glucosyl moiety of maltose to acceptors with alcoholic OH groups.

Biochem/physiol Actions

Maltose phosphorylase (MP) is a dimeric enzyme that catalyzes maltose and inorganic phosphate into β-D-glucose-1-phosphate and glucose.
Maltose phosphorylase not only transfers glucosyl moieties from maltose to other sugars but has been shown to also use phenolic compounds such as salicyl alcohol as acceptors.
Enzymatically converts maltose to D-Glucose.

Unit Definition

One unit will produce 1.0 μmole of D-Glucose from maltose per minute at pH 7.0 at 30°C.

Other Notes

Contains lactose.
