EGZ is the major endoglucanase secreted by Erwinia chrysanthemi. Functional characterization indicates that it is made of a catalytic N-terminal domain linked to a C-terminal cellulose-binding domain (CBD) by a Ser/Thr-rich linker. A chimeric plasmid, in which the CBD-encoding region was fused downstream of the ompA signal sequence, was constructed and introduced into Escherichia coli. This allowed for the production of processed and disulfide-bonded CBD, mostly recovered from the culture supernatant of E. coli. One-dimensional NMR analysis of the purified CBD reveals that it folds into a well-structured domain. Moreover, comparison with the one-dimensional NMR analysis of full-length EGZ strongly suggests that the CBD folds autonomously, providing experimental support for the existence of domains of EGZ.
