Presence of Maltodextrins in Potato Phosphorylase Preparations

Abstract

IN the presence of excess α-D-glucose-1-phosphate (α-D-G-1-P) potato phosphorylase catalyses the in vitro synthesis of amylose-like polysaccharides by 1 : 4 linking of glucose residues to the non-reducing ends of malto-dextrin primer molecules, either added or present as impurities in the reactants. Maltotriose is the smallest molecule which will act as a primer for the synthesis1. The action pattern of the enzyme has been shown to be of the ‘multichain’ type over a wide range of conditions1.
