The effect of exogenous sugars on the control of flux by adenosine 5'-diphosphoglucose pyrophosphorylase in potato tuber discs.

Journal article

The aim of this work was to investigate the effect of exogenous sugars on the extent to which starch synthesis in potato ( Solanum tuberosum L.) is controlled by adenosine 5'-diphosphoglucose pyrophosphorylase (EC 2.7.7.27; AGPase). Tuber discs were incubated in the presence of a range of concentrations of glucose and sucrose, and metabolic fluxes measured following the supply of [U-14C]glucose and measurement of the specific radioactivity of the hexose phosphate pool. In the presence of gluc...
