Abstract:Stimulation of encystation of Entamoeba invadens by incubation of trophozoites under glucose-limiting conditions brought about a dramatic fall of ornithine decarboxylase activity, a key enzyme in polyamine biosynthesis. Levels of enzyme specific activity after 24 and 48 h of encystation represented only 11% and 1.3%, respectively, of those detected at the start of incubation. Induction of encystation in the presence of exogenously added polyamines resulted in a marked reduction in cyst formation. Thus, after 7… Show more
