Design Notes
This is a short and simply to clone sequence. When we added His-Tags on this protein, this was added on the C-terminus. Also the mRNA was tagged on the 3' part on a fluorescent aptamer, which did not affect protein expression.
During the cloning of this part we accidently inserted a mutation on DNA position 27. A cytosin was mutated to an alanin. This changes the amino acid sequence on position 9 from a phenylalanin (F) to a leucin (L). This Mutation does not affect protein functionality, solvability nor brightness, nor did we realise any other change of characteristics.
Source
The protein sequence was obtained from Goedhart, J. et al., (2012), codon optimized for E.Coli and ordered as a g-Block by IDT. Sequence can be found on PDB:3ZTF; POI: 10.2210/pdb3ZTF/pdb. However, without the K206A mutation.
