1,4‐μ‐Glucan synthase activity, but not 1,3‐μ‐glucan‐synthase activity, from Saprolegnia monoica was stimulated by cyclic‐diguanylic acid, an immediate activator of Acetobacter xylinum ‐ cellulose synthase. This activator, which increased the V max without modifying the K m for UDP‐glucose, was active on solubilized and partially purified enzymes. These results suggest that the fungal system shares a common regulatory mechanism with the bacterial system.
