THE SEPARATION OF CELLULOSE-BINDING DOMAIN FROM ENDOGLUCANASE EGL-II BY PROTEOLYSIS METHOD
View through CrossRef
Protein molecule of endoglucanase Egl-II is consisted of two domains, namely cellulose-binding domain (CBD) which serves in promoting the adsorption of the enzyme to the insoluble crystalline cellulose and cellulase catalytic domain which is responsible for the hydrolysis reaction. In this study, CBD of endoglucanase Egl-II was separated from the intact protein by degradation using the papain and then separation by ultrafiltration methods. The CBD resulted can be used to modify the waste paper fibers. The results of electrophoresis before degradation showed that endoglucanase Egl-II has a molecular weight about 57.5 kDa. The electrophoregram after protein degradation and separation of CBD from the endoglucanase Egl-II showed that CBD was separated from the intact protein with a molecular weight about 21 kDa. The yield of CBDs were 59.51%. It can be concluded that CBD of endoglucanase Egl-II can be separated from the intact protein.Keywords: endoglucanase Egl-II, cellulose-binding domain, papain, ultrafiltration.
