Literature summary for 3.2.1.8 extracted from
- Cloning of a rumen fungal xylanase gene and purification of the recombinant enzyme via artificial oil bodies (2008), Appl. Microbiol. Biotechnol., 79, 225-233.
Activating Compound
| Activating Compound | Comment | Organism | Structure |
|---|---|---|---|
| additional information | in the insoluble fraction of cell lysate or embedding in artificial oil bodies, XynS20-intein M-oleosin does not show any enzymatic activity. After release from artificial oil bodies by inclusion of DTT to induce intein linker self-splicing, XynS20 reveals a xylanase activity band of about 36 kDa | Neocallimastix patriciarum |
Cloned(Commentary)

|---|---|
| DNA fragments of xynS20 genes subcloned into vector pOSP2. XynS20 expressed as a recombinant protein fused to the N-terminus of oleosin by a linker polypeptide, intein M, in Escherichia coli | Neocallimastix patriciarum |
