Allgemeine Beschreibung

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.[1]

Anwendung

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.[2]
Maltose phosphorylase from Enterococcus has been used in a study to describe a new pathway for maltose utilization in lactic acid bacteria.[3] It has also been used in a study to describe the transfer of glucosyl moiety of maltose to acceptors with alcoholic OH groups.[4]

Biochem./physiol. Wirkung

Enzymatically converts maltose to D-Glucose.
Maltose phosphorylase (MP) is a dimeric enzyme that catalyzes maltose and inorganic phosphate into β-D-glucose-1-phosphate and glucose. [1]
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.[4]

Einheitendefinition

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

Sonstige Hinweise

Contains lactose.

Maltose metabolism is initiated by an ATP-dependent permease system in Lactococcus lactis. The subsequent degradation of intracellular maltose is performed by the concerted action of Pi-dependent maltose phosphorylase and beta-phosphoglucomutase. In some Gram-positive bacteria, maltose metabolism is regulated by a

Maltose phosphorylase (MP) is a dimeric enzyme that catalyzes the conversion of maltose and inorganic phosphate into beta-D-glucose-1-phosphate and glucose without requiring any cofactors, such as pyridoxal phosphate. The enzyme is part of operons that are involved in maltose/malto-oligosaccharide metabolism.
