K12 e.coli native Manganese Superoxide Dismutase

Coding sequence for the enzyme Mn-SOD or SoDA. This protein catalyzes the dismutation of superoxide, a free radical. Sequence found by converting the amino acid sequence of Mn-SOD protein native to Escherichia coli, the organism for which it is also optimized for.

Our composite part BBa_K3523005 contains the basic part BBa_K3523000, which sequence has optimized differently from the sequence of other two similar basic part BBa_M36071 and BBa_K2638106 (Fig1). Apart from that, we add a T7 promoter, His tag, and a T7 terminator to develop our composite part BBa_K3523005.

Usage and Biology

Superoxide dismutase cataylyzes the dismutation of superoxide. Superoxide is produced naturally in the respiration process. It causes damage to the cell by altering lipid structure and breaking down proteins among other negative effects. This gene provides the protein to transform two superoxide molecules into hydrogen peroxide and oxygen.

Design Notes

This DNA sequence is converted from the amino acid sequence of Mn-SOD protein using the online converter from In-Silico. We optimized our sequence in DNA 2.0's Gene Designer by increasing GC content and minimizing repeats. We accomplished this by altering basepairs without altering amino acids.
