KEGG Pathway containing Chitinase: Aminosugars Metabolism
The pathway above is labeled for a halophile, haloarcula marismortui (most of the other halophiles on KEGG did not have a reference pathway for Aminosugars Metabolism). As you can see, Chitinase (EC#:3.2.1.14) is not predicted for this halophile.
The only automated annotation database to predict a Chitinase was Manatee. Manatee predicted Chitinase A at 55855...57810. Chitinase A: Manatee

As you can see, Chitinase A is not among the top hits. However, there is one hit for it further down the list:
