Part:BBa_K422014
mCyPet (AarI A-part)
Biological Background
CyPet is an evolutionary optimized cyan fluorescent protein CFP developed in 2005 by Nguyen and Daugherty. They showed the FRET pair CyPet-YPet to have a 7-fold higher ratiometric FRET signal change than their parental pair.
mCyPet has a mutation in A206K preventing it from forming dimers (Ohashi et al., 20007).
Characterization
mCyPet has a distinct fluorescence spectra. Measured at an excitation wavelength of 425 nm with a Fluorescein High Precision Monochromator, maximum emission is detected at 482 nm. Figure 1 shows the relative fluorescene units of mCyPet over a wavelenght range of 460 to 560 nm.
Cloning strategy
BBF RFC28: A method for combinatorial multi-part assembly based on the Type IIs restriction enzyme AarI. mCyPet-A is an A-part compatible for N-Terminal fusion. For more information see [http://2010.igem.org/Team:ETHZ_Basel/Biology/Cloning].
