MotB Strep-tag SilkSubunitE1 SilkSubunitE2

This biobrick contains signal sequence MotB attached to silk subunit E1 with an N-terminal strep tag and silk subunit E2.

The MotB codes for the signal sequence of flagellar motor protein MotB.

The Strep-tag, fused at the N-terminal, is used both as a binding tag to use to indicate its production and as a binding component to Streptavidin.

Subunit N1 codes for a spider silk protein that is optimized for maximal expression in Bacillus subtilis 168. The primary goal of the algorithm was to optimize the codon selection based on their availability scores. The secondary goal was to prevent the formation of secondary RNA structures in close proximity to the RBS, and the tertiary goal was to minimize the number of restriction sites.

The amino acid sequence is based on the adapted MaSp2 sequences described in the paper of Brooks et. al. 2008.
