Electrophoretic studies on enzymes in Paragonimus spp

III. Variation of glucosephosphate isomerase (GPI) in a natural population of P, iloktsuenensis

Abstract

Electrophoretic studies were carried out on glucosephosphate isomerase (GPI) in a parasitic helminth, Paragonimus iloktsuenensis, using starch gel electrophoresis. It was found that GPI isozymes are highly polymorphic in a natural population. From the observed distribution of phenotypes of banding patterns, it was considered that GPI isozymes have a dimeric structure and are controlled by a single locus with three codominant alleles.
