Gene cloning and protein expression
We optimized the gene codon of rabbit cytochrome P450 2E1 (CYP2E1) based on Bacillus subtilis codon usage preference and synthesized the DNA fragment by Twist Bioscience. Then, DNA fragments were amplified by PCR and assembled with a terminator, followed by inserting to PliaI-RBS/pSB1C3.

To express CYP2E1 gene in Bacillus subtilis, we transfer the DNA fragments of PliaI-RBS-CYP2E1-Tr to pBS0E vector and transformed Bacillus subtilis 168 with the resulting plasmids.
