description

Abstract 1. 1. Octopine dehydrogenase catalyses the reductive condensation of pyruvate and arginine to produce octopine in mollusc tissues. 2. 2. In all Bivalvia species studied to date, a single polymorphic locus, anodally migrating, was demonstrated. 3. 3. We studied, by starch gel electrophoresis, octopine isozymes in Tapes decussatus tissues. 4. 4. A polymorphic anodal form is present in adductor muscle, foot muscle, mantle and gill. 5. 5. A hepatopancreas-specific form, cathodally migrating, is also evident.
