Next Generation Synthesis

Week 04: Use synthesized oligonucleotide primers to amplify a PCR product. Assemble a library of protein variants from the PCR amplicons using Gibson Assembly.

We will be changing the color-generating chromophore of the purple Acropora millepora chromoprotein (amilCP) to a variety of orange, pink, and blue mutants. These divergently-colored genetic variants of amilCP were described by Liljeruhm et al. in 2018. Their strategy to identify where to mutate amilCP was inferred by sequence similarities to the chromophore region that allows for spectral engineering of the structurally-characterized and well-known green fluorescent protein (GFP), which is native to the jellyfish Aequorea victoria (From the experiment protocol).
