What is the Km of the chitin binding domain?
The Bacillus circulans CBD binds only high MW chitin that is insoluble, making binding kinetics difficult to determine. At this time binding studies have not been conducted, and the only known way to elute the CBD fusion is by denaturation, for example, with 0.3 M NaOH, 1%SDS or 6M Guanidinium hydrochloride.
