PHOSPHORYLATION OF MARTOTRIOSE WITH INORGANIC CYCLO-TRIPHOSPHATE

Abstract

The phosphorylation of maltotriose by cyclo-triphosphate (P_3m) proceeded on not only 1-OH group of a reducing unit, but also 2′-OH and 2″-OH of nonreducing units in aqueous solution. The optimum condition for the phosphorylation of maltotriose with P_3m was a molar ratio of P_3m: maltotriose =1: 4, pH 12, and 25°C.
