D-Enzyme (4-alpha-glucanotransferase, EC 2.4.1.25) from cultured symbiotic Nostoc and Chlorella has been partially purified and characterized. The enzyme catalyzes the disproportionation of maltooligosaccharides and is able to form maltooligosaccharides from soluble starch and D-glucose. The properties of D-enzyme from Nostoc and Chlorella are similar with respect to substrate specificity, K-M values and pH dependence, but differ with respect to temperature optimum and molecular weight (40 degrees C/50 kDa and 50 degrees C/230 kDa for the enzyme from Nostoc and Chlorella, respectively). D-enzyme activity has been demonstrated also in free-living Anabaena, Chlorella and Chlamydomonas. Its physiological role in symbiotic Nostoc is briefly discussed.
