The periplasmic cyclodextrin binding protein CymE from Klebsiella oxytoca and its role in maltodextrin and cyclodextrin transport

The periplasmic cyclodextrin binding protein CymE from Klebsiella oxytoca was characterized and analyzed. Chromatographic techniques were used to analyze the bacterial strains. Alpha-cyclodextrin, beta-cyclodextrin and gamma-cyclodextrin was easily bound by CymE. The K. oxytoca cym system efficienty metabolized alpha-cyclodextrin compared to the ability of the E. coli maltose system to take up maltohexaose.
