Design

This part was generated in a modified version of RFC25, where a strong Shine Dalgarno Sequence (SD) is included, and has the following prefix and suffix:

Prefix with EcoRI, NotI, XbaI and SD GAATTCGCGGCCGCTTCTAGATAAGGAGGTCAAAA
Suffix with AgeI, SpeI, NotI and PstI ACCGGTTAATACTAGTAGCGGCCGCTGCAGA

Sites of restriction enzymes generating compatible overhangs are indicated by sharing one color. (EcoRI and PstI are marked in blue, NotI in green, XbaI and SpeI in red and AgeI in orange. Additionally, the Shine-Dalgarno sequence is marked in silver and the stop codon is underlined.)

This part was designed to meet the needs of the Signal Peptide Toolbox which was created by the [http://2017.igem.org/Team:TU_Dresden iGEM Team TU Dresden 2017 (EncaBcillus - It's a trap!)].

Source

The YlqB signal peptide of B. subtilis inhibitor of entry into sporulation was amplified via PCR from the B. subtilis wild type W168 genome using the primers listed below.

Following amplification, the signal peptide was digested using EcoRI and PstI and ligated into pSB1C3.
