Design Notes

The RBS sequence used in this part can be found in several B. subtilis genes and is known to efficiently initiate translation. The spacer sequence between the RBS and start codon originates form the B. subtilis wapA gene. The CDS was optimized for B. subtilis by the GenScript OptimumGeneTM software (see images).

Frequency of optimal codons before optimization. The x-axis 100 value is set for the codon with the highest usage frequency for a given amino acid in B. subtilis.
Frequency of optimal codons after optimization. The x-axis 100 value is set for the codon with the highest usage frequency for a given amino acid in B. subtilis.


Structural Prediction

Structural prediction of the protein without the signaling sequence by [http://zhanglab.ccmb.med.umich.edu/I-TASSER/ I-TASSER] yielded the following results. No tertiary structure has been identified by x-ray crystallography or NMR.
