Team:Toulouse/Result/parts

As the chassis B. subtilis is not as used as E. coli, it was sometimes hard for us to get or find desired parts.
However, in collaboration with other iGEM teams and with a synthesis compagny, we managed to obtain or make the following parts:

Submitted parts

We have deposed 16 new BioBrick parts to the Registry. All of them were cloned into the standard plasmid pSB1C3, tested and sequenced.

Chemotaxis

- BBa_K1364000:N-acetylglucosamine based chemotaxis for Bacillus subtilis

This part is designed to enable a N-acetylglucosamine based chemotaxis in Bacillus subtilis.

Design:

The encoded protein is a chimera of two proteins:
- the methyl accepting Chemotaxis protein (McpA from Bacillus subtilis which is required for taxis towards glucose.
- the N-acetylglucosamine regulated methyl-accepting chemotaxis protein from Vibrio cholerae (VCD).

The chimeric protein contains the intracellular domains of McpA from Bacillus subtilis to enable the transduction of the signal: these domains correspond to the amino acids 1-37 and 282-610. The extracellular domain of VCD is inserted between the intracellular regions of McpA to sense N-acetylglucosamine and corresponds to the amino acids 31-310.

Binding

- BBa_K1364005: P_veg + Chitin Binding Cell Wall protein

This part is designed to enable the binding of Bacillus subtilis to the fungi wall made of chitin.

Design:

This part is composed of a Cell Wall Binding (CWB) sequence and a Chitin Binding Domain (CBD) linked with a 6 amino acids linker.

The CWB domain has been extracted from LytC (BBa_K316030) of the iGEM 2010 Imperial College team.
The CBD is composed of the Domain 4 of the GbpA protein of Vibrio cholerae, a protein reported to mediate bacterial attachment to chitin. It has been shown that the Domain 4 was essential to bind chitin.
