Background
The mechanical properties of spider silk are a result of its primary amino acid sequence. Although the amino acid sequences for various types of spider silk are well documented, it is still relatively unknown how these amino acids aggregate and contribute to the strength and stability of silk. Silk proteins are composed of repeats of short amino acid sequences (approximately 33 amino acids). These repeats can be referred to as monomers. Each monomer consists of a glycine rich stretch, followed by an alanine rich stretch. It is hypothesized that these hydrophobic alanines form beta sheet crystals with other silk proteins, and contribute to the strength of the silk fibers. The glycine stretches are thought to form alpha helices and contribute to the flexibility of the protein. This monomer sequence is repeated many times in one protein, and allow for strong interactions with other silk proteins. These simple motifs repeated over and over are the key to the formation of one of the strongest materials known to man.

|
Tell us more about your project. Give us background. Use this as the abstract of your project. Be descriptive but concise (1-2 paragraphs) ReferencesiGEM teams are encouraged to record references you use during the course of your research. They should be posted somewhere on your wiki so that judges and other visitors can see how you though about your project and what works inspired you. |
You can use these subtopics to further explain your project
It's important for teams to describe all the creativity that goes into an iGEM project, along with all the great ideas your team will come up with over the course of your work. It's also important to clearly describe your achievements so that judges will know what you tried to do and where you succeeded. Please write your project page such that what you achieved is easy to distinguish from what you attempted. |
