Aipotu(II) BioChemistry Protein Pigments
- Given that "red" phenylalanine and "blue" tryptophan amino acids are responsible for their respective pigments, their combination into the same protein sequence will fold into a true-expressing purple protein pigment.
- Part 1
- The aipotu biochemistry tool was utilized to isolate certain target pigments and the pertinent findings were as follows:
- In the first run of the program initial discovery of the blue pigment came from the pigment combination in the "Green-2" flower color (Image A).
- As the next combination came about the red pigment discovery was located in the red flower pigment combination (Image B).
- phenylalanine and tryptophan pigements together produced a purple flower but not a purple protein.
- Tyrptophan and phenylalanine's structures were examined and both of the constituents functional groups where found to be non-polar amino acids.
- Part 2
- Once the pigment amino acids were isolated a new protein was constructed.
- The respectiveTyrptophan and phenylalanine amino acids were added in succession within the same amino acid sequence.
- The program was run with the new sequence and the suggested protein was folded, yielding the true purple pigment.
- Analysis of the successful protein was conducted.
- The process described in the in the Experiment section exhibited two major findings: One was that a purple flower can be produced by combining the amino acid sequences responsible for the red and purple pigment. Although this produced a purple phenotype the pigment itself was a co dominant expression of alleles it was not a fundamentally purple pigment. However the true purple pigment desired was produced when the amino acids (red) phenylalanine and (blue) tryptophan were placed together within the same sequence. These two amino acids' R groups are aromatic and thus conjugated systems indicating their ability to absorb light and be responsible for the pigment color.
Based upon the findings in the Experiment section and detail in the Results section the hypothesis is supported that purple pigment is the combination of the aromatic red and blue amino acids.
This assignment and modeling experiment was conducted in tandem with Shivum Desai and Mia Huddleston and they assisted with the collaborative work aspect and helped model the layout of this individual journal entry.
