Literature summary for 3.1.1.14 extracted from
- Characterization of sol-gel entrapped chlorophyllase (2006), Biotechnol. Bioeng., 95, 840-849.
Activating Compound
| Activating Compound | Comment | Organism | Structure |
|---|---|---|---|
| acetone | the activity of entrapped chlorophyllase increased with increasing acetone concentration from 6.5 to 20%, however, further increase of acetone leads to a decrease in chlorophyllase activity. Free chlorophyllase reaches its highest activity at acetone concentration of 10% in a medium consisting of water, acetone, and canola oil, overview | Phaeodactylum tricornutum |  |
Protein Variants

| additional information | entrapping of the enzyme in tetramethoxysilane-based sol-gel in the presence of lipid, acetone is used to introduce the substrate-chlorophyll into aqueous reaction medium in solubilized form, the entrapped chlorophyllase is less sensitive toward the denaturing effect of acetone in the bulk phase than the free enzyme, sol-gel at wet-stage, diffusion coefficient and partition coefficient of chlorophyll in sol-gel, overview | Phaeodactylum tricornutum |
Inhibitors
| Inhibitors | Comment | Organism | Structure |
|---|---|---|---|
| canola oil | presence of 10%, 20%, and 30% of canola oil decreased the activity of entrapped chlorophyllase by 60%, 75%, and 80%, respectively | Phaeodactylum tricornutum |
