About our modeling

為了能夠使我們更有效地拿到我們的指定抗菌肽，我們在設計序列時在AMPs的N-terminal加上了來自S.lividans的signal peptide。這個signal peptide在經過periplasmic space時會被peptidase辨認並且做切割。Peptidase會辨認signal peptide與相聯蛋白相接處的雙Ala，然後從中間將兩者分開。為了使peptidase能夠順利辨認signal peptide與target AMPs，我們在AMP的N-terminal多加了一個Ala氨基酸，供給辨認的切位點。 我們利用模擬技術，利用原本的已知結構，去推測在我們多加了一個Ala的情況下，是否會影響AMPs的蛋白結構折疊。

In order to make us more efficient to get our peptide，so when we design our AMPs’s N-terminal.We add the signal peptide from S.lividans.When the signal peptide go through the periplasmic space, peptidase will identified it and cut. Peptidase will identified signal peptide and connection protein’s double Ala at convergence. Then separate two parts. In order to make peptidase can be more success to identify signal peptide and target AMPs. We add an Ala attach N-terminal in our AMP.To identify cutting site.

We ues protein secondary structure prediction,used known peptide structure.To surmise,if we add more Ala, whether it will affect our AMPs ‘protein structure folding.
Signiferin
 with Ala attach
N-terminal
Signiferin
 without Ala attach
N-terminal
The 2nd column result shows most of our AMP corresponding seconadry Structure state are helix. and third column shows probability of correct prediction.

Conclusion

Signiferin以及Epinicidin-1都是由 a helix結構所構成，在我們的模擬分析後（寫上用什麼軟體分析），不管是signiferin還是Epinecidin-1在N-terminal多加了一個Ala後並不影響蛋白的摺疊結構。

Through the protein secondary structure prediction. The result shows both of Signiferin and Epinicidin-1 are a helix structure. Whatever is signiferin or Epinicidin-1,after we add an ala N-terminal, it won’t affect our AMPs ‘protein structure folding.
