the Chitosanase web page

Welcome to the first www page dedicated to the enzymatic hydrolysis of chitosan. The purpose of this page is to present up-to-date information about the hydrolytic enzymes acting on chitosan and derivatives.
Another page from our laboratory:
The cytosine deaminase negative selection system: click here
