Optimized DpnI

It is an enzyme which could cut all methylated DNA so that engineering bacteria may die in a certain situation. It could be used to ensure bio-safety.

Bacillus subminis has been increasingly applied in genetic engineered due to its powerful secretion capacity.

As a restriction enzyme which is capable of cutting all methylated DNA, DPNI can be applied to Bacillus subtilis in the way of synthetic biology to control the environment by taking advantage of its DNA eradication.

The histograms show the percentage of sequence codons which fall into a certain quality class. The quality value of the most frequently used codon for a given amino acid in the desired expression system is set to 100, the remaining codons are scaled accordingly (see also Sharp, P.M., Li, W.H., Nucleic Acids Res. 15 (3),1987).

                                 Fig.3. Codon quality plot                                                         Fig.4. Optimized codon quality plot

The plots show the quality of the used codon at the indicated codon position.

The plots show the GC content in a 40 bp window centered at the indicated nucleotide position.
