Production of trehalose phosphorylase by Catellatospora ferruginea

Abstract A range of microorganisms was screened for new and high producer strains of trehalose phosphorylase (EC 2.4.1.64). Trehalose phosphorylase activity was found in cells of actinomycetes of the genera Actinomadura, Amycolata, Catellatospora, Kineosporia , and Nocardia . Among them, Catellatospora ferruginea showed the highest enzyme activity. Trehalose phosphorylase from C. ferruginea was able to catalyse both the phosphorolysis of trehalose into β-glucose 1-phosphate and d-glucose and the synthesis of trehalose from β-glucose 1-phosphate and d-glucose.
