Descrição geral
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.
Aplicação
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
Ações bioquímicas/fisiológicas
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.
Definição da unidade
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.

The concentration of pyrophosphate in urine has been determined using the enzyme uridine-5'-diphosphoglucose pyrophosphorylase. The technique is relatively quick and easy to perform. Reproducibility of results was good, and results from recovery experiments were excellent. The mean concentration of pyrophosphate

Plant pyrophosphorylases that are capable of producing UDP-sugars, key precursors for glycosylation reactions, include UDP-glucose pyrophosphorylases (A- and B-type), UDP-sugar pyrophosphorylase and UDP-N-acetylglucosamine pyrophosphorylase. Although not sharing significant homology at the amino acid sequence level, the proteins share a common
