Four hundred and fifty-four subjects with hyperamylasaemia were screened for the presence of macroamylase using polyethylene glycol precipitation (PEG) and the Beckman automated amylase assay based on the hydrolysis of maltotetraose. Twenty-five subjects (5.5%) exhibited PEG precipitation values suggestive of

Glucoamylases are inverting exo-acting starch hydrolases releasing beta-glucose from the non-reducing ends of starch and related substrates. The majority of glucoamylases are multidomain enzymes consisting of a catalytic domain connected to a starch-binding domain by an O-glycosylated linker region. Three-dimensional
