Design Notes

The sequence of OmpA is MKKTAIAIAVALAGFATVAQA.Using the GeneOptimizer online tool developed by ThermoFisher, we performed codon optimization and converted the protein sequence of OmpA into a DNA sequence (ATGAAAAAGACCGCAATTGCCATTGCAGTTGCACTGGCAGGTTTTGCAACCGTTGCACAGGCA) which is most suitable for expression in Escherichia coli. OmpA signal peptide should be fused at the N terminal of target protein.
