Fructose 2,6-bisphosphate, a potent regulator of carbohydrate metabolism, inhibits trehalose phosphorylase from protist Euglena gracilis.

Abstract:

:Partially purified trehalose phosphorylase (EC 2.4.1.64) from Euglena gracilis SM-ZK was inhibited by fructose 2,6-bisphosphate in both synthetic and degradative directions. Ki value for trehalose phosphorolysis was 1.2 microM and that for trehalose synthesis was 0.5 microM. Functions of fructose 2,6-bisphosphate in Euglena, particularly in the regulative mechanism of the two reserve carbohydrates, paramylon and trehalose, are discussed.
