KEGG Pathway containing Chitinase: Aminosugars Metabolism Pathway.png
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
The top BlastP results: Blastpr.png

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

So, although it is possible that Chitinase is coded for by this region, there is a stronger possibility that it is not.


While doing some hand-curated annotations, we also found another potential chitinase-coding region at 72986...74821 (+). Two hits were found by Blastp that coded for chitinase, they were the 2nd and 3rd hits overall and both were from halophiles:
First Chitinase hit: ChitinaseBlast.png

Second Chitinase hit: ChitinaseBlast2.png

So, data from this coding region strongly suggest the coding of chitinase in our organism. However, we do not yet have any physiological data to support the presence of chitinase.
