xynD, which produces xylanase

Axh43 gene, also called xynD, is derived from Bacillus subtilis 168 and belongs to the GH43 hydrolase family. It can specifically hydrolyze the Arabinose residues on the O-2 xylan or o-3 xylan, and assist the hydrolysis of the xylan.


Usage and Biology

In our project, we use this part together with xynA gene BBa_K1175005 to hydrolyze xylan and produce arabinose. For more information, please check out our part BBa_K3447102.

Design

Design Notes

There is no need to pay attention.

Source

This gene is derived from Bacillus subtilis 168, we get the genomic sequence by NCBI.
We ordered the part DNA from a synthesis company.
