Cellulase

Legend:
Green: H. utahensis has the enzyme
Red: "H. utahensis" does not have the enzyme
Blue: Pathway
Purple: Molecule or Protein
Enzyme 3.2.1.4 is the cellulase
Enzyme 3.2.1.19 is the cellobiohydrolase
Enzyme 3.2.1.12 is the beta-glucosidase
I think it would be interesting to directly test for the enzymes highlighted in red and allow the organism to grow in the absence of glucose. I think that performing these two experiments will give us a lot of insight into how this organism produces glucose, because if we see that the organism can grow in the absence of the glucose and that it doesn't have some of these enzymes highlighted in red, this would suggest that this organism might have a different pathway for breaking down cellulose.
