Description
General description
Uridine-5′-diphosphoglucose pyrophosphorylase (UDP-glc-PPase) is ubiquitous in plants, yeast, bacteria, and mammals. This enzyme is an octamer of eight identical sub-units.
Application
Uridine-5′-diphosphoglucose pyrophosphorylase from baker′s yeast has been used:in the synthesis of uridine-5′-diphosphoglucose (UDP-Glc)-¹³C9
to quantify Suc synthase (SUS) enzyme activity in rice
to study the role of hexokinase and glycogen synthase controls the flux in frog oocytes
Biochem/physiol Actions
Uridine-5′-diphosphoglucose pyrophosphorylase (UDP-glc-PPase) participates in catalyzing the synthesis of UDP-glucose. This enzyme requires divalent cations such as Mg²⁺, Ca²⁺, Mn²⁺, Ni²⁺ for its activity.
Physical form
Lyophilized, sulfate-free powder containing citrate buffer salt
Other Notes
One unit will form 1.0 μmole of glucose 1-phosphate from uridine-5′-diphosphoglucose and inorganic pyrophosphate per min at pH 7.6 at 25 °C.
