CapD_CP

A circularly permuted [http://www.parts.igem.org/Part:BBa_K314011 CapD] with a Foldit-designed linker.

Usage and Biology

To test BBa _K314012, it was inserted into a pET29b+ vector using [http://2010.igem.org/Team:Washington/Protocols/KunkelCapD Kunkel's Mutagenesis]. CapD_CP was then produced and purified as described in the [http://2010.igem.org/Team:Washington/Protocols/50mLPurificationCapD UW 2010 iGEM Team's Small Scale Protein Purification Protocol]. The purified protein was then tested for activity. For a detailed description of the assay, please see the [http://2010.igem.org/Team:Washington/Protocols/EnzymeAssayCapD 2010 UW iGEM wiki]. A protein gel was also run to determine physical qualities. The resulting data is shown below.

Kinetic constants, kcat and Km, taken from our plotted curves are shown in the table above.


We also ran the purified protein samples through a mass spectrometer to make sure the first methionine was being removed by the natural E. coli methionine aminopeptidase and that the protein was the expected size. Our results indicate that a massive majority of the protein in our purified sample was within .02% error of the predicted CapD_CP size. Expected weight of CapD_CP without Methionine=55285Da, with Methionine=55417Da. Our mass spec detected a peak at 55274.8Da (no Methionine) well within the 0.02% error limit for our mass spec
