additional information
-
sigmoidal kinetics is observed with mixtures of artifactual beta 60 capsids and alpha subunit trimers. Km value for lumazine of the lumazine synthase/riboflavin synthase complex is about 10 times larger as compared to light riboflavin synthase consisting of alpha subunits, without lumazine synthase activity
