Abstract
Summary
α-d-Glucosyl fluoride, a stereoanalog of α-d-glucopyranose, parallels sucrose in serving as an effective substrate for dextransucrase. Its polymerization to soluble dextran by L. mesenteroides enzyme, and to water-insoluble dextran gels by enzymes from certain endocarditis streptococci (Streptococcus var. DS); are the first known examples of enzymic polysaccharide synthesis from a donor substrate lacking a glycosidic linkage.
