Design Notes
An additional ATG is needed at the start of the sequence. The amino acid sequence of the signal peptide was deduced from the DNA sequence as follows: Met-Lys-Lys-Thr-Ala-Ile-Ala-Ile-Ala-Val-Ala-Leu-Ala-Gly-Phe-Ala-Thr-Val-Ala-Gin-Ala.
Source
The original part comes from an article by Movva, N. R., Nakamura, K., & Inouye, M., 1980 [1].The amino acid sequence complies with all the features of the loop model proposed for the mechanism of protein secretion across the cytoplasmic membrane..
