The biologically active form of this protein is proposed to be a
.
We would like to make fluorescent mutants for microscopy applications. One way to do this is by attaching maleimide dye to Cys amino acids present in the protein. The homodimer has . (Cys is orange.) Before designing the mutant we need to check that there are for maleimide attachment. Because Cys 82 looks to be accessible and also because the placement of Cys 66 looks like attaching a fluorophore to it may interfere with membrane binding we will mutate . This will be done for each monomer, . The mutation will replace the cysteines at residue 66 with . (Ala is purple.) Each of the mutated monomers will now have only one binding site at .
