  • Title: A bifunctional exoglucanase-endoglucanase fusion protein.
    Author: Warren RA, Gerhard B, Gilkes NR, Owolabi JB, Kilburn DG, Miller RC.
    Journal: Gene; 1987; 61(3):421-7. PubMed ID: 3128463.
    Abstract:
    A fusion was constructed between the cex gene of Cellulomonas fimi, which encodes an exoglucanase, and the cenA gene of the same organism, which encodes an endoglucanase. The cex-cenA fusion was expressed in Escherichia coli to give a fusion protein with both exoglucanase and endoglucanase activities. The fusion protein, unlike the cex and the cenA gene products from E. coli, did not bind to microcrystalline cellulose, presumably because it lacked an intact substrate-binding region. The fusion protein was exported to the periplasm in E. coli.
