The chitinase gene chiA was identified on the Clostridium thermocellum genome downstream of the endoglucanase gene celA. It contains a catalytic module of glycosyl hydrolase family 18 and a cellulosomal dockerin module. Chi18A hydrolyzes aryl-acetyl-chito-oligosaccharides preferentially. In denaturing electrophoresis of purified cellulosomes, a single chitinase activity band was identified in zymograms and Western blots, indicating that Chi18A is the only chitinase in the cellulosome.
