Abstract
Abstract Upon treatment of whole filaments of Anabaena variabilis with a French pressure cell, the activity of sucrose synthase (UDP glucose; D-fructose 2-α-ᴅ-glucosyl transferase, EC 2.4.1.13) was found to be associated almost exclusively with the vegetative cells. The sucrose-cleaving enzyme, an alkaline invertase (β-ᴅ-fructofuranoside fructohydrolase, EC 3.2.1.26), appears to be localized solely within the heterocysts. The implications of these findings, in the light of relevant data from the literature, are summarized in a model representing the physiological differentiation and molecular exchange between vegetative cells and heterocysts.
